    Thanks for sticking with me Mr. Tubs. I did blow air through the mixture screw and it does blow through the float bowl and the main jet. I also sprayed carb cleaner through the same way to make sure it is clean, then blew air through again. This is why I am confused. I believe I have all the ports clean but it still acts like something is clogged. ?????

    Unless there is a port I am not aware of, I thought I had everything clean.
    Maybe it is no longer a carb issue. Maybe the o-ring fixed the carb problem and it is now something else? But I have no idea what that other problem could be! It could be that I’m an idiot too!!! Naaaaaa… that can’t be! 🙂

    [i]The O Ring is only a solution for the fuel squirting out from the top of the pump.
    I am not familiar with that carburetor and am at a loss as to what could be causing the issue you are experiencing.[/i]

    The more difficult the challenge the bigger the reward. What
    was the most turns out that you tried on the mixture screw.[/i]

    I am having a similar issue with a similar motor.
    Did you ever solve your problem?
    Ever figure out ow that check valve works? The one at the bottom of the float bowl?
    Fuel comes out of the pump on mine too, but I’ve chalked that up to the fact that fuel comes out of everywhere on motors older the 1954.
    Ha!
    I’m hoping by restarting this topic, because there are pictures of what I tried to discribe in my own, some ones memory will be jogged.
    It’s a common enough motor, but info seems to be lacking.
    Thanks,
    G
