    just got together my second build, started up first try and when I give throttle it doesn't let off and would go faster. I checked the carb and the plunger piece fully opens and closes. I am 99% sure it's an air leak. How can I fix it? I have it on an off set intake manifold but I have to jam it on to make it fit and when I put it on the stock manifold the carb is croked to the right due to the throttle cable. Will answer and try anything at this point thanks!

    Could be a crank gasket or intake gasket?

    Does it have power loss?

    Could be carb is adjusted wrong?

    Could be that its running lean?

    I need more info to give a certain diagnosis.
