Several things could cause that. All related to "tuning issues"... Old fuel. Is this fuel left over from last year ? That's the No.1 no-no. Carb needs idle mixture adjustments, or "idle circuit" inside carb is Old spark plug, plug fouling, plug burned to wide spark gap, other plug issues...

>> Was there a wash down recently, where water could have gotten into the fuel ? I'm thinking maybe you hit it with the garden hose to knock the pollen off and didn't think anything of it. That would explain the run, then no-run scenario. It does not explain the apparent loss of electrical...

If the tank is above the carb, then YES... if... while you have the hose disconnected you check for fuel flow by letting a couple of tablespoons of fuel squirt out of the hose. However, the pump may also serve the disguised purpose of being a automatic fuel cut off. With the tank higher than...

You shouldn't need to take the engine apart !! :ROFLMAO:

I don't suggest you stop the mower that way ! :ROFLMAO: Sorry, I couldn't help myself. And the pull cord feels the same before and after this massage ? I think you are flooding the engine with fuel when you tilt the mower up to turn the blade. I believe turning the engine is actually doing...

A model number might help us help you.

Welcome ! Was this the first run of the season ? Or has it been cranked and run within the last month, say late Feb or early March. If it was the first crank of the season, then what was done to prep it for winter storage ?

With a test light or VOM check the small terminal on the starter solenoid for the presence of 12V when you turn the ignition key to "Start". > If you do have power, then the solenoid needs checking. > If you do not have power, then the ignition switch (or whatever switch incorporates the "Start"...

Hello, James. Welcome.

1. The vacuum inside the line is lower than you think. The reinforced, double-wall of SAE J30 fuel line is more than strong enough to stand up to being used on a fuel vacuum line. That's what Exmark uses on my mower with a 22HP V-twin engine. That's what's on my B&S 7kW home generator uses...

I'd measure the required length. Then go to Lowes and walk myself over the spring assortments. Reality Check: It's a spring, not piston rings.

And then there's the ecological way...

Dielectric grease is great on new equipment, before trouble starts. But since it only stops new water from causing new corrosion it's not great. Probably work, but not the best. Look up the word "dielectric" in the dictionary and you'll start to understand.

Just let it burn off. There's minimal fire hazard. If the neighbors complain, tell them you're fogging for mosquitos. Of course, we'll need to send the Mower Police around tomorrow to check your Oil Change License, but those fines typically run under $400. Hope this helps.

The Hondas I'm familiar with the pull cord is just the pull cord and rewind spring. The ratchet sits atop the engine fan. Because of its location, the ratchet can get filled with bits of grass and leaves from mowing. You're supposed to blow all that AND the top of he engine off once a year. Use...

The Wattage will usually be printed on the bulbs or the wrapper they come in. The cheapest and brightest way to go is with the new LED lamps. You'll get more light and yet draw down your battery less by using LEDs. What ever bulb you decide upon, it must be 12V. Are the headlamps already wired...

White smoke is oil burning. • He's either grossly over-filled the engine. (Some is good, but more is never better.) • Or he's running some super-thin car oil in it. (Air-cooled engines run much hotter so the weight is critical.) • Or he poured the replacement oil into the wrong engine hole or...

A year outside in the weather (under a tarp simply intensifies the humidity) followed by a bath. Smells like a gross case of terminal corrosion. It's most probably on several contact points, not simply one. That's why it's hard to find and/or diagnose. Look at these 3 places.... • Inside the...

Did you perhaps wash this mower after the first run ? Can you tell what brand of engine is on this unit ? Can you post photos ?

This is a common issue, so you are not alone. Let me begin by telling you what NOT to do. Don't get ham-fisted and try to force it. What will happen then is that you'll break off the spigot, and then you'll be buying a new cowling for your engine. In my limited experience it's best to first...

I will go further than that. Anytime you are not mowing you should have the fuel valve turned to OFF. If you are very conscientious, then you will turn the fuel OFF as soon as you leave the lawn... as you walk the mower back to the garage or car. In this way the fluid level inside the carb is...

Welcome ! My first thought is that your belts are slipping, and that smell is from very hot belts... not the exhaust. The belts can feel "tight" to the 'pull test' and you might suppose that is enough. But belts also need to be soft in order to grip the sheaves. As belts age, they also harden...

It might have a different bolt to denote a LH thread on that spindle... if the direction of rotation varies on that one blade.

Advanced ignition timing will have that effect at starting RPM. The ignition occurs before TDC, so the piston is pushed backwards. The pull cord ratchets are designed for one direction of rotation, so when the engine turns the opposite direction the cord gets abruptly yanked back.

Typically, you have a filter to remove the small debris from the hydraulic fluid. The problem is simpler than that. You change your fluids on a calendar basis due to WATER. These large cases experience internal condensation with the changes of seasons. This might not be an issue for the pro...

Some ideas... You can't lap the valves and get 100% contact on the valve and the seat if the valve is bent. You could have the adjuster on the intake valve too tight, or your valve timing can be off, thus forcing the valve to leak. You stated you ran this test at TDC. But you did not state...

^ This ^ and/or the friction of "going fast" has exceeded the power transmission capability of the common V-belt. In their proper power range V-belts rarely slip, but there is a limit. This is when you need roller chain and sprockets, or "toothed belts". But even these have their limits. If the...

• Sometimes the adjustment is directly to the idle Mixture, where the adjustment screw adjusts the amount of fuel. • Sometimes the fuel-to-air mixture is set by a small jet, and then an adjustment screw adjusts the Volume of mixture. So the idle jet could be clear, and yet the hidden screw...

Tell all the teens in the neighborhood that it's good stuff to smoke. It will be gone in 3 days. ?

Change the oil, if you haven't all ready. Could be something stupid simple like that.

Here's one of us doing it the correct way... :ROFLMAO:

I want to be like you guys when I grow up. I inflated my fronts to 20psi. I think I like it better than 13psi. No animals were hurt during this inflation test.

You are correct. Customers always appreciate mechanics trying to save them money on any job, until the unit breaks again 2 weeks later. Then they become downright abusive and you loose a customer. It's a delicate balance. If I had to run the risk of doing this job again for free if I didn't...

I tend to agree with Bert, somewhat. The true indicator to me is NOT the physical float position, but rather how the engine runs on the available mixture that fuel level produces. Do you feel or hear engine surging ? Is the spark plug white or colorless ? Yes, that float needle will produce a...

The problem is 2 fold: 1) The fuel tank is ABOVE the carb. Therefore GRAVITY (which has not been turned off in a LONG time) will always be trying (yes, even while you sleep) to push gasoline into the engine oil... where it can ruin your fine engine. So you DO NEED a fuel shut off. This is...

Most carbs have adjustments on the idle mixture. On carbs made since about 1995, these adjustments are set at the factory and then capped or covered to comply with EPA regs. The final opening is so tiny that idle settings are always the first to gum up as Ethanol fuel ages. I highly suggest you...

True. High speed jet is adjusted first because idle is such a tiny percentage of that. 2. On a 4-stroke I adjust idle mixture for maximum engine speed. (Max RPM is indicative of the most efficient burn. At idle no one cares about "mixture", the major concern is to stay running.) 3. Lastly...

That is so ancient !! Get with the program, Slomo. You should be using Slicker 60 at a minimum, or the new Slickest 70.

My 2020 Exmark manual lists 13psi the correct pressure in the "Front Caster - All Models" (that covers 44" to 60"), size 13x5.00-6. Tire pressures are only listed in the front of the manual in the Specifications section.

All of the above is predicated on the idea that there is no fuel in the tank OR carb that is over 6 weeks old. You MUST be using fresh fuel.

Got a link you can share ???

This is the type equipment I buy at Tractor Supply... if you have one near you. They'll have several designs in the $150 range.

Tractor Supply sells Purolator brand filters in my area. Their blue filters are higher rated than the ones colored red, but they are all top rated.

If it's not the seat switch, then maybe one of the similar switches on the hand brake or op lever position. A schematic will tell you what the other switches are (electrically) in the same circuit with the seat switch. Those switches would be tested in the same way. A schematic will not tell...

Welcome. Unlike garden tractors, all ZTMs will more easily slide when traversing a hill. Be VERY careful on wet grass, or near features like lakes. Lots of safety videos on YouTube you can/should watch.

That looks to be a fuel filter. No clicking coming from that unit unless aliens have laid their eggs inside. Start with a wash job. Life is too short to work on dirty engines. :ROFLMAO: Sounds like a dead battery, but lots more information is needed.

BAD idea ! Remove the filter and blow compressed air through it in REVERSE direction if you want to unclog it, but most definitely re-install the filter.

Welcome ! There's your problem right there. Your mower simply wants to move to Texas. ?
