    Just so we all know what engine you are talking about, post
    the engine's model, type, and code numbers.

    What khouse is referring to is a bowl in the top of
    the tank, directly under the carb. On real bad
    cases, rust pinholes can develop in this bowl making
    for hard starting. Remove the tank and carb and
    disassemble it and make sure your problem is not
    here first. To do a proper valve job requires special
    tools anyway, lapping does not give a good repair.

    Fish is right must have a valve machine to get right angle. I have one they are not cheap. take it to a qualified machine shop. it shouldn't need any of this unless the engine has at least 10000 hrs on it

    Thanks everyone for your input. Seeing that we got 21 cm of snow yesterday I had some time to tinker with it.(Gotta love Winnipeg in the spring) I cleaned out the pick up filter. It was pretty dirty, and I repalced the diaphragm. It seemed to be stretched a bit. I also took off the flywheel to check the key and it was fine. I tend to believe at this point it must be the valves. It still doesnt start without pulling it for a 1/2 hour when cold. I'm starting to look like Popeye on my right side.
