    Gentlemen, Rob, Dutch 1 and piston slapper,

    Thank you for all of your expertise. This AM I did a volume test on the fuel pump and it is pumping out 9 ounces in 15 seconds, 3 times better that the manual suggests.

    However, I have new problems. The engine surges and I have to use the choke to keep it running and I am getting an occasional backfire. I assume that is from the excess use of the choke. As suggested, I sprayed all around the carb and heads. No improvement in the running of the engine. I checked all of the hoses (air and fuel lines) and they are in excellent condition.

    Also, this AM I could not get the engine to run with the air filter installed. After removing the filter, which is new I could get the engine running. The engine stalls immediately if you engage the mower.

    Currently, I am at a loss as to what to do next. But, I am leaving tomorrow morning on a 2 week vacation. Maybe, by the time I get back the tractor will have repaired itself. LOL

    Any further recommendations are gratefully accepted.

    Thanks again,

    Vernon

    Your problem certainly appears to be fuel related but if you feel assured that everything fuel related is up to snuff, I'd consider a leakdown and compression test.

    I have done a copression test and it is within specifications, but have not done a leakdown test.

    Thanks

    Readjust the governor....
    Replace the intake gaskets....

    Vernon L did you ever get the 335 fixed as I have one that does exactly as you described yours is doing.
