OK, now that we understand each other.... (Brings back the thought of Churchill's famous quote..) 1. The float valve really can't restrain that much fuel "pressure". The modern float needles with the viton tip do better than the older metal and nylon versions, but still the "pressure limit" on...

You've got an issue with fuel flow. When you disconnect the fuel hose from the carb, then a full diameter stream should shoot out of the fuel line, if the tank is held above the carb. You'll want to check over the entire fuel system... Breathers inside the fuel cap get clogged with ethanol...

Suggestions for cut quality... Engine should be running near max or at max to get the blade speed very high. Look at the condition of the blades as far as the winglets that lift the grass. Look under the deck to make sure there's no clogging. Air for lifting the grass often enters from the top...

Rather than guess, simply disconnect the wire to the carb and then install a new fuse. Replacing the electronic shut-off with a manual fuel valve will accomplish the same end with a lot less guessing. And for a lot less money.

IF there is no way to physically remove the jet, THEN they must be cleaned in-situ... just like I said. This type carb design/manufacturing is becoming more common. They simply want you to buy a new carb every year.

You are ALL crazy ! The jets on tiny carbs found on small engines are so finely tuned that any metal object will gouge the soft brass and make the engine run richer. Just because you get away with it doesn't mean it's not happening. Just because you can't see it doesn't mean it's not happening...

The fuel level should be about 1/8" below the float bowl gasket, which would place it about 1/4" below the interior of the carb.... So YES, your float level is WAY too high. A good rule is to turn OFF the fuel when you finish mowing and allow the engine continue to run as you walk back to the...

My tire pressures are not listed in the Specifications section of my manual. I found the information elsewhere in the manual.

That "lawn mower guy" is clueless. The very first thing you learn on the very first day is: "Black smoke is Rich fuel condition. White smoke is burning oil."

You have shortened the engine's life, but by how much no one can say. If you disassembled the engine, you probably couldn't even measure the differences. But these engines are like Pepperidge Farm.... they remember ! Start using the fuel valve. It's on there for a reason, and now you know the...

I think the OP's fuel is at fault. A new mower would indeed run about 3 days on the first tank of fuel. Then he adds his own fuel and things start to go wrong. Twice at exactly the same time. That's not a coincidence, that's a reason. The proof of this is he's too quick to blame the store...

This or a Lazy-Boy !! :ROFLMAO:

Another missing Stickie... instructing first time posters to be sure and log the brand, model, model number and some photos.

You think I'm aggressive, just wait until DFACS knocks on your door with the police in tow. Those people are more aggressive than the IRS. I know, I used to work with them. All I'm asking is that you re-think your safety measures for the sake of your grandson. Not my grandson, YOURS.

Most jets are cleaned in-situ. Those few that unscrew are obvious from their hex shape or screwdriver slot. Most modern float needles are tipped with soft viton, making float needle replacement MORE common, and float needle seat wear a thing of the past.

No one here is going to help you defeat safety measures that help protect young and innocent operators like your grandson. Most any profession your grandson might dream of, from policeman to surgeon, would be completely ended by the loss of just 2 fingers. And mower accidents happen to children...

Unlike USA carbs, your model seems to have an idle circuit as witnessed by the screw we see prominently displayed in the middle of photo #1 and 2. Engines may RUN on the main jet, but they actually start on the IDLE circuit. So you'll want to remove that screw and blow carb cleaner through that...

How old is your grandson ?

Just saw this. Watch and see how a mass of grass clippings could jam the governor....

I'd believe the governor simply came out of adjustment before I'd believe a spring went "bad".

You could always stretch a pair of your wife's panty hose over the motor. But the neighbors may laugh. :ROFLMAO:

The fool left Ethanol fuel in the fuel system over the winter. Now the engine can't get enough fuel without the choke. You're going to need to dis-assemble the entire fuel system and clean or replace everything.... from the fuel cap to the carb. This includes the fuel lines, manual fuel valve...

• In my part of the country, Ethanol fuel can go "bad" in as little as 8 weeks. Especially if the vehicle is left stationary. The mere fact that you asked makes me extremely uneasy. If you have doubts, then change it. • Lots of things can cause the engine to knock. Start with tightening every...

Thanks for the parts visual. • No screw on your model, that was a 60's & 70's thing. • No fuel pump, your model is gravity-fed. That makes it very important to check flow, because there is NO pressure. When you unplug the fuel line from the carb, do you get a "drip, drip", or a solid stream of...

A commercial mower who needs to worry about their annual fuel bills might want EFI. A residential owner who wants to do his own service work would most definitely want a carb.

Nothing is "straightforward". :ROFLMAO: Different models may have different blade mounting shaft diameters or shaft lengths which may not be apparent at first glance. Some advanced detailed measurements would be in order.

No need to ask us, or look for one on Ebay because a 72" deck is WAY too large AND heavy to ship. Better to check your local CraigsList or FB Marketplace, or better yet hoof it on down to your local Hustler dealer and simply buy it new.

How is it you know exactly where the valve are set, but were guessing at the c/s position ? And why are you guessing at the oil level.... when "oil" was the initial complaint ? There's nothing quite like a guessing game where the guest withholds key information, and makes up answers as they...

I think you were at TDC.... on the Exhaust stroke. The piston has a hole in it, and so the oil came through the piston and out the Ex valve, which is open on that stroke.

That's what I'm thinking too. Some kind of anti-tip safety switch that's not set right, or maybe no longer mounted to the frame. Could be flopping around on the harness. Anyway, it reads the downhill as a tip-over and cuts the ignition. If it was oil or gas related it would do a lot of...

Generic dirt bike air filters for motorcycle racing might be an answer. They are cheap and typically fit many carb sizes. They come with a radiator band clamp that can tighten down on most any size carb. Click this.... Generic Dirt Bike AF from Walmart

.07 acres = 3050 sq. ft., or 101 x 30ft. Burt's has a great idea. Put it mostly in garden in the flat areas, with perennial ground cover on the slopes. Lots of things you can grow so easily and offset your grocery bill... plus it tastes better. Your wife will love it. DO NOT plant English ivy...

Battery sounds nice, but I see too many problem reports. IMHO, battery mowers are simply NOT ready for "prime time". If it's not battery issues, then it's charger issues. The mowers are like battery drills. Right when you need a new battery pack, they stop making that model to introduce a new...

Two choices: Go back to engineering school and then work 20 years in the hydraulic design industry. Follow the instructions.

Agreed. Surging caused by a lean condition. Suggestions... Adjust the main jet screw (if present) Check for air leaks. (Loose carb mounting ? Aging manifold gasket ?) Clean the carb. Leaving Ethanol fuels in the carb can coat the fixed size jets, making them run leaner. Wallowed out butterfly...

1. Your float system is bad, which allows an immoderately high fuel level. Not high enough to leak, but higher than required so that the choke draws in too much fuel. OR 2. Your air filter needs replacing. Inability for air to enter means that more fuel is ingested, in the place of air.

What possessed this idiot to make a video of himself working on a machine he knows nothing about ? "Watch this yall, while I wear my Crocs to operate an open blade trimmer."

Could have fallen out of the muffler bearing. :ROFLMAO:

I highly doubt that. There is always a "reason". Your main job is to find it, or it will simply happen again.

It's a good bet the spring does not anchor to the belt, as the diagram shows !! :ROFLMAO: Attach the spring to the tensioner arm. The anchor point will be such that the spring is at 90 degrees (a right angle) to the tensioner arm, and at a distance about 1.2X the length of the relaxed spring...

I had a boss that used to say, "Time to take the gas cap off and put it on a new one !"

You mean "bad" as in it's involved in under-age drinking, or "bad" as in it mugs little old ladies on the subway at night ?? Can you describe what this term means ? And how does the problem reveal itself ?

You are obviously trying to sell a new belt to simply enrich yourself, when it is painfully obvious THAT belt has at least 10 more good years. :ROFLMAO:

Joey - Questions... What is the age in years and hours run on this mower ? How old is the fuel ? Is old fuel mixed with new fuel, or did you completely empty the fuel system over the winter ? Have you checked the condition of the flywheel key ? Is the top of the engine and the surrounding area...

To a point, true.... but.... The level of the engine oil should never be up to the level of a horizontal cylinder bore or it would smoke continuously, even when new. There are oil control rings and compression rings. Compression rings will easily pass oil, which is why the second type ring its...

Sorry, I've never met him. :ROFLMAO:

Probably barking up the wrong tree. I'm not saying your coil is good or bad, but about 95% of these "won't start" issues are related to winter storage with ethanol fuel in the fuel system. When the owner tries to start the mower the plug gets fouled.... permanently. 1. Start by emptying EVERY...

And who gave you this sage advice? A neighbor, your mother-in-law, a guy you never saw before ?? What if I said it's most likely the breather hose that powers the fuel pump. A $2 / 10 minute repair ??

Lovely machine. You'll really like it. Some of the features you won't really appreciate until you get some hours on it. Everything is easy to reach and service. Two modifications I made... 1. The fuel line runs under the bulkhead behind the seat. If you'll unplug the line from the Fuel Valve...
