Are you saying that it won't get passed idle at all without stalling? Try to rev it up with the choke on. If this works it sounds like you still have water in the carb. Drain the bowl and see if it helps.
If its working some passed idle then it may not be water but just a piece of trash in the carb. I've seen carbs get 3 cleanings before they started working correctly again. It doesn't take but a tiny piece of grit to stop one up. Is it idling fine?
you will likely have to rejet.
To know which way (i suspect your are going to have to go down in jet size)
partially cover the snorkel with your hand and see if it revs any better. if so, you are lean and u need more fuel.
if it makes it worse you need more air. You guys used 1.5" tubing im guessing?
