This is bad advice. Don't pay any attention to this guy. CHANGE the oil, making sure you refill with the correct quantity, then mow some more with it.

Drain the oil back to the correct level and mow some more with it. What do you have to lose?

Only two ways for oil to get out of the engine--leaks or the exhaust. I don't see how it could use that much oil and not smoke unless it's leaking. The spark plug should tell you if the oil is going out the exhaust.

Those aren't lubricating qualities.

What's your spark plug look like?

I would think 2 stroke oil would have the fewest demands placed on it of any oil. It's job is to lube the crank bearing and cylinder walls for one revolution. Then it's replaced by new oil.

Not going to argue with you. Use what you like.

I removed the link. Please explain further the circumstances of how you obtained your settlement. The post looks very much like spam without more explanation.

Between me and my Dad, we've owned three Cub Cadets over the years. I still have #3, but I wouldn't buy a new one. I don't think they're as good as they used to be.

Better check the oil level, too. If it sat for an hour without any needle valve in it, that gas had to go somewhere.

Go get some more bourbon. It may start when you get back. I think hot start issues are mostly spark related. I've had mowers that, once started, you'd better finish the job because they would not start again until they cooled off. I never bothered to trace the problem because they would...

I haven't seen any blade bolts that weren't right hand threads, meaning you tighten them by turning clockwise as you face the bolt. To loosen, turn them counter clockwise.

Don't mess with the air filter until it needs to be replaced. Believe it or not, the dirtier they get, pleated paper filters do a better job of filtering. If you don't have a restriction indicator (aka 'Filter Minder') installed, follow the manufacturer's recommendation for replacement. But...

There are only two things a diesel needs to make full power--fuel and air. How's the air filter?

Is the 722D a diesel? If so, when was the last time you replaced the fuel filter?

Another little known fuel fact: Higher octane fuel has a lower specific gravity than lower octane fuels. Who cares? Probably nobody but that means you're paying more to get fewer BTU's per gallon. Simply put, if your engine doesn't require it, you'll burn more of that expensive fuel to do...

Correct, higher octane will not improve performance unless the compression ratio of the engine is high enough to require it. But higher octane fuels generally have different additives, such as the quantity of detergent in the higher priced fuels.

Hard to do when you're on a motorcycle that needs Premium. It would be interesting to know just how much of the previous grade of fuel you get when switching from regular to premium.

Agree 100%.

Welcome to the forum. How does this translate to reciprocating engines?

Can you see in the tank to tell if there is any contamination in there? After reading about the problems that person had with the gas powered Kubota Zero Turn, I would make sure the tank doesn't have any debris in it. All the symptoms point to fuel starvation. I don't know how much trouble...

Did that tube have any kind of a screen on it?

Here's the thread: https://www.lawnmowerforum.com/threads/solved-kommander-zt-fuel-problems-sputtering-stalling-etc.47223/#post-359422 Look at the debris in that tube. Yours may have a similar fuel pickup. I won't be around until late afternoon if you have questions but there are plenty of...

cambre, read this. This is from another post that has a 'similar' problem. It's a Kubota gas mower, but the problem is similar to yours: Sharing this public service announcement for what it's worth as my local dealer says they've seen it on a number of the Kommander ZT's. I have a 2013...

I have thought about it. If the fuel cutoff is electric, the engine will die abruptly when that electricity is cut off, not wind down as the OP describes.

If it starts on its own, the injection system does not need bleeding. What is happening is the fuel flow to the injection pump is slightly less that what the engine needs to run. You can test this with a small container of diesel to replace the tank. A gallon or two will be plenty. Run the...

I DON'T think it's getting air in the system. If it was, you'd have to go through the whole bleeding process every time it dies. Let me get this straight--When it dies, you don't have to do anything other than let it sit for awhile before you can start it again? If that's the case, something...

The reason I ask is, if the engine runs--then dies--and can be restarted, something is restricting the flow of fuel prior to it getting to the injection pump. It would not restart if it had gotten air in the system. If it starts, the injection system is primed. Since replacing the fuel pump...

When it dies, does it slowly wind down or does it stop abruptly, as it does when you shut it down?

I assumed the head(s) were still on the engine. They weren't?

Does it do this on a repeated basis? By that I mean it hits once and you try again an hour or a day later and it does the same thing? Get another spark plug and swap it out when it does the 'one and done' thing.

That Walmart oil has no diesel classification approval, if that matters to the user. FWIW, you can buy good, gasoline and diesel rated oil such as the Rotella T-4 that Buddy mentioned for around $3 a quart ($12/gallon).

I've never worked on an OHV Kohler, so keep that in mind. There'll be more than one way to do this. Here's one: Take the spark plug out. Turn the crankshaft to lower the piston in the cylinder. Make sure it's the BDC in which the intake valve has just closed. Insert some small rope through...

One of the jobs of engine oil is to clean the engine by holding the contaminants in suspension so that they will be taken out of the engine when the oil is drained. 'Black' motor oil is not a bad thing. It's evidence that that the oil is doing its job of holding contaminants in suspension.

Ask your question. There have been other chainsaw questions on here.

Talk to your county ag agent or someone who has knowledge of your area, but I'll bet the best time will be in the Fall.

If it has half the power that it used to have, that means it's getting half the fuel it used to get. Fuel flow restriction--or air--in the system will cause this. I would start it and just let it run at about 1500 rpm and see if it shuts off again.

Don't connect a line from the tank to the injection pump without a filter between the two. Injection pumps do not tolerate any dirt in the fuel.

NGK has achieved enough brand recognition that counterfeits may be appearing.

I would, too, but not all two cycle engines have them. I have an old Toro/Suzuki push mower and the shop manual calls for Threebond #1104 or Loctite #515. The OP's engine had a gasket though, and to not use a gasket would decrease crankshaft endplay, One good thing about making gaskets is...

cambre, I'm at a loss. Was it idling for ten minutes or running at full speed? Does it have an electric fuel shut off to kill the engine?

Can't help you on finding a factory gasket. Is it possible to make one or use a silicon compound?

How much do you want to spend, $2500 or $25,000?

I remember the first (and only) time I carried a hidden gun. This was a long time ago, as my telling will make it obvious. I had to meet some men, whom I knew absolutely nothing about, to collect a reward for stolen airplane. Since I thought it would be better to have a gun and not need it...

Is the fuel tank below the fuel filter? If it is, you'll have to have the fuel pump running to get fuel to come out of that bleed screw on the fuel filter. If you can't get fuel to come out of that bleed screw, there is something wrong between that point and the tank. edit: I returned the...

There's a difference between and 'injector' and an 'injection pump.' I'm having a hard time visualizing what you are doing and what you've changed on your mower. First, you've replaced the factory fuel filter arrangement, which was a primary/secondary filter system, with a spin-on filter...

Is the 'bleed bolt' the same as the one on the pictures I sent you? If it is, leave it open a little longer (with the engine running) and see if you can increase engine rpm. Shut the bleed screw gradually and reopen it if the engine starts to die again. I would do this for a minute or two and...

Yes, it's down on the corner of 9th and Broadway, called Booga-Booga Meadows. I find cutting out paper dolls to be quite relaxing. Looking forward to a new friend. I'm not acquainted with a 'canister assembly.' What is it? Diesel engines only need two things to run--Hot air and fuel...
