My Toro 6 5 Will Start When Primed but Will Stop Quickly and Will Not Start Until Primed Again

Ahhh…the olfactory property of fresh-cutting grass. There's really nothing like it. Yet, it's pretty frustrating to be all ready to tackle those tall green blades only to have your mower fire upwardly and and so sputter out. If your lawn mower starts then dies, y'all desire a quick answer about what's to blame, and what to do to set it. I'll share the four nigh common causes to this mower problem and what y'all need to exercise to accost each.

When your mower starts then dies it can feel similar you lot're lone, only this trouble is more common than you might retrieve, and the prepare tin be an like shooting fish in a barrel one.

Let'southward have a look at the four well-nigh common reasons behind that fake start and how to prepare them.

Causes for Lawn Mower Starting then Dying

If your lawn mower starts, runs briefly, then dies these are the four most common reasons that's happening:

• Muddy carburetor / chock-full carburetor basin
• Old gasoline that has gone bad
• Dirty or lacking spark plugs
• Too much oil in your resevoir

Below I'll become into each potential problem, why it can result in a mower that starts then dies, and what you should do to fix it.

Dirty Carburetor or Clogged Carburetor Bowl

When your backyard mower starts and so dies, your carburetor is well-nigh probable involved somehow.

Think almost it. If you live in a northern region, your mower sits all wintertime … waiting months without whatever action.

And, if yous live in a more temperate zone, your mower works hard year-around.

In both cases, your carburetor is going to need a little TLC.

What'southward so of import virtually the carburetor?

Your engine needs a steady catamenia of gasoline to run correctly. The carburetor is responsible for mixing gas with just the right amount of oxygen to create combustion.

This combustion supplies a continuous rotation of the crankshaft that is necessary to run the mower's engine.

If your carburetor is dingy or the carburetor bowl is chock-full, the process higher up is compromised, and your engine may start upward, simply it will not run properly and may dice before long after you pull the cord.

How do I prepare it?

Your dirty carburetor needs a good blowout with an aerosol can of carburetor cleaner. This will price you lot less than $x and will terminal for a flavor or two. I use the WD-twoscore Specialist Fast Acting Carb/Throttle Body Parts Cleaner (Amazon link). This cleaner uses a solvent formula to breakup carbon contaminants, leaving your carburetor clean and gum-free. I give my mower a shot of that every time a mow, correct earlier pulling the cord, and recommend that you do the same.

The only drawback to this particular cleaner is information technology does not have a straw for targeted spraying. If you need a more precise application, Gumout makes a cleaner (Amazon link) that will practice the fox with its jet spray applicator.

You can purchase either product locally, or online.

Now for the procedure.

Unscrew the carburetor bowl and give it a in one case over with the cleaner. Exist sure to make clean the spiral and pigsty with the carburetor cleaner every bit well. This is where the directional spraying straw is particularly handy. When reattaching the bowl, don't over-tighten the screw. This could strip the threads enough to distort the seal.

What I Practice

For carb maintenance, give a light spray well-nigh the air intake hole for your mower'southward engine just before you lot starting time it up. This is typically merely behind the air filter. Remove the filter, give the hole a spray, and then replace the filter.

When you first the mower, it'll be pulled into the engine and make clean deposits in your carb.

Sometime Gasoline in Your Mower

Yous know your mower can't run without gasoline, but the quality of the gas is equally of import.

If the gas in your mower has been sitting inactive for a while, evaporation has nearly probable created a damaging residue.

This residue leaves particles that clog your mower'due south internal parts.

The end result is restricted gas flow, which ways your mower can first and die shortly thereafter. Sometimes, your mower won't start at all.

How do I gear up information technology?

If your mower tank is less than half full of former gas, yous might try adding new gas to dilute the impurities. If the old gas is more than one-half of a tank, it would exist best to siphon it out and fill the tank with fresh gasoline.

In both cases, adding a stabilizer such as Sta-bil Fuel System Stabilizer (Amazon link) is a smart idea. Stabilizers prevent the bottleneck remainder for up to two years, and at around $10 a canteen, they are an inexpensive additive that can go on your mower running like a champ.

Always read the directions to know the proper fuel to stabilizer ratio for your mower.

What I Exercise

I used to mix Sta-bil into my fuel, only now I just pay a little extra for 4-cycle TruFuel – an ethanol free gas product that tin can sit for years without going bad.

It'southward more expensive than regular gas mixed with Sta-bil, but a couple of larger cans will get my Honda cocky-propelled mower (this one from Home Depot if yous're curious) through the mowing season upwardly here in New England, and I like the peace of mind that comes with knowing my mower and snowfall blower always start on the kickoff pull, and I don't have to worry about bad gas giving me problems when I'm fix to mow or need to clear the driveway.

You lot tin buy information technology online, or locally at Home Depot or some local hardware stores.

Muddy or Defective Spark Plugs

Spark plugs supply the "spark" that ignites the air/fuel mixture in your engine.

This pocket-sized explosion makes your engine produce power.

The spark plugs are an essential component of your mower'due south ignition organisation. If they are dirty or faulty, they volition not spark, and your mower volition not start, or may showtime and so quickly die.

How do I gear up it?

Your mower's spark plug(s) are piece of cake to notice. In nigh walk-behind mowers they're covered with a blackness cable and right in the front of your mower.

You'll demand a socket wrench of the right size to remove your plug (check your manual to find the correct size for your mower/spark plug).

If your spark plugs are non too heavily coated with build-up, you tin can try cleaning them. Yous should never clean a spark plug with a shot-blasting cleaner. A wire brush and appropriate cleaner will practise the play tricks if the plug is just dirty.

Nonetheless, if your mower's spark plug looks filthy or appears to accept a night carbon rest, yous might be better off replacing.

This is an easy job and information technology's cheap – a new spark plug with be $viii-9 and your size is probably available locally.

What I Do

Spark plugs should exist replaced every yr or two for problem-gratis mowing, and I practice mine annually as part of my jump mower maintenance.

I get a new air filter and change the oil in my mower at the same time. This runs me about $twenty total, takes me about xv minutes, and keeps my mower in perfect working status.

Replacing Your Spark Plug

Removing your spark plug is an easy task anyone can do. Merely unhook the spark plug wire and remove the old plug with a spark plug socket.

Replacing a spark plug tin be a fleck more than challenging for a first-timer, simply I still consider information technology an easy chore.

Use a spark plug gauge to measure the gap between the ii electrodes at the tip of your spark plug. Check for the specifications for your model to know the recommended size of the gap.

If necessary, employ a spark plug guess to adjust the gap by gently bending the curved electrode. When the gap is correct, the guess will drag a bit as you pull it through the gap.

Now you can install the new plug and attach the spark plug lead. Be careful non to over-tighten on installation.

If you have never washed this before, there are several videos online that can be of not bad assistance, only my communication is that as shortly equally it starts to feel snug, requite it no more another quarter plough to prevent damage.

Too Much Oil in the Mower's Reservoir

If your carburetor is clean and the spark plugs are firing, the problem might be likewise much oil.

I believe it's homo nature to want to over-fill a backyard mower's oil reservoir, especially if you're non specially handy. Y'all experience and so accomplished that we're doing the job yourself that yous go overboard and over-fill up the tank.

Information technology happens, and information technology's not the end of the world (or your mower).

White smoke coming out of the engine is a tell-tale sign that excessive oil is the culprit.

If a lot of smoke is coming out, your mower might be running, but non for long. In this case, the excess oil will eventually drown out the engine and cause it to die.

How exercise I fix it?

This is actually an easy ready. If you lot take as well much oil, yous only need to drain some. Y'all can use a siphon, or (if you have a walk-behind mower) you tin tip your mower and bleed the oil from the hole where y'all add it.

What I Do

I'grand guilty of overfilling the oil tank sometimes too, so I've learned to go slow when I add oil. I check, and check again with the dipstick and gradually bring the level up to the proper identify.

If you have overfilled your oil tank, I advise that y'all employ a dipstick to measure the corporeality of oil in the reservoir before removing it, and then again after to make sure you get the right level.

Not plenty oil is another (and more serious) trouble, and you would not want to inadvertently trade one effect for another.

After draining some oil and checking to come across if you lot have an acceptable amount, starting time the mower once more.

If the mower fires and stays running without the billowing puffs of white fume, yous take corrected your problem.

Lawn Mower Starts Then Dies: When it'southward Time to Call a Professional

If y'all have tested all of the methods I've shared for fixing your backyard mower that starts and then dies, hopefully your trouble is solved.

But if non, it might be time to throw in the shop towel and call a professional.

The post-obit are other issues that could be keeping your mower from running properly.

More than Serious Reasons Your Lawn Mower Starts And so Dies

1. Worn out carburetor:  If your carburetor is more than than dirty, it might exist time to replace information technology.
2. Faulty choke: Unless you are extremely handy, identifying this trouble and restoring the frail rest necessary to get your engine purring similar a kitten is another event for the experts.
3. Gas tank or gas line blockage: Anytime your gasoline is not getting to the engine, your mower volition not run properly. A blockage of any kind that prevents the constant flow of gas is a trouble that might take a trained eye to identify and fix.

The average weekend warrior with limited knowledge on the matter will probably feel more comfortable hiring someone with the experience and the tools to get the job done correct.

I recommend that yous start past checking your mower'southward warranty. If it's covered, a repair may not cost you annihilation. Some companies will transport someone correct to your home, or come to pick up your mower to save you time.

If your mower isn't covered by warranty, find a local pocket-size-engine repair shop that has good reviews. These guys can set nigh anything, and their prices are typically lower than you lot'd expect.

Preventing Mower Problems

The best manner to ensure your mower will fire upwardly and run similar a gnaw is to put preventative measures in place.

I have tips for winterizing your mower, and a spring maintenance checklist that you tin can bank check out if you'd like to larn more than.

To summarize those hither, however:

1. Clean your air filter regularly (replace it annually).
2. Change your spark plugs every 1-ii years.
3. Keep stored oil and gasoline make clean. Use a stabilizer in your gas to keep it fresh for upwards to ii years, or pay extra for 4-cycle TruFuel.
4. Go on your engine clean with an engine degreaser.
5. Use the dipstick and don't overfill your oil reservoir.
6. Keep your carburetor clean with a carburetor cleaner spray.

Performing regular maintenance on your mower is the best style to continue information technology running smoothly, and investing a few bucks per year in this is worth information technology.

You'll avoid headaches, repair costs, and your mower volition last a long fourth dimension, starting right up when you lot need it.

If you do meet a trouble with your lawn mower, decide if you are comfy with trying to gear up it yourself.

If the result seems to be something beyond the nuts, don't hesitate to call a professional. There's no shame in this, and sometimes do-it-yourself repairs are just non worth the time, energy, or frustration.

Just if you are up for the challenge of fixing the problem yourself, the above guidelines provide a good starting place, and online videos may also be useful. I think YouTube is a great resource.

The main thing is that you get your mower stock-still so y'all can become out there and brand your lawn the envy of the neighborhood.
