    Can you describe what happens in more detail. When it cranks once what exactly do you mean, just one rotation?

    Yes one rotation and nothing? I taped the side of the starter but that did nothing ether and I do not hear any clicking sounds. The red Wire from the battery to the starter is warm also

    Use a jumper cable and go directly from the battery to the starter. It should spin immediately, if not your starter is shot. Obviously make sure the blades are not engaged and its in neutral with the clutch/brake depressed and someone sitting in the seat

    Hi,
    It is the valves and the ACR not working. Give the YouTube video link.
    Peace,

    Hi,
    It is unlikely the starter unless you have burned it up trying to crank it. It is a 7/16" nut for the cable and two 1/2" bolts for the starter, though they also have T-30 torx sockets in them.
    It is however the valves, look back for valve questions answered by "ballengerb1" to find a YouTube video on adjustment first. VERY common on that engine, though you are supposed to only have to adjust once for the life of the engine (according to the factory) barring a rocker arm failure. That engine has had camshaft and rocker arm heat-treating problems. The first far more than the latter.

    Thank you for that answer it was not the starter I did get it off and jump it out and it worked just fine OK so what is the problem I'll tell you I took out the spark plug and gas ran out so I turned the motor over a few times by hand put it all back together jumped started it and it ran like charm. I'm glad I have a place to go to get answers like this I'm sure I will need you guys again LOL

    Hi,
    Change your oil, I'll bet it is full of gas. Just takes a few minutes of warm-up to start blowing past the rings at the bottom of the cylinder and do that.

    How did the gas get into the oil?? Not sure what you are saying here ( Just takes a few minutes of warm-up to start blowing past the rings at the bottom of the cylinder and do that.)

    Hi,
    The easy answer is the same way it got into the cylinder. If the inlet needle in the carb does not seal and the intake valve is open; it will run into the cylinder and beneath the rings. Check the oil for level and the smell of gas.
    Other things can do it, also. Tipping the machine. Bad vent in the filler cap to the fuel tank.
    Tipping the wrong way can also ruin the air filter by soaking it with fuel and/or oil and restricting the air flow subsequently.
