carb help!!!

I don't think it's that it needs a rebuild so much as it needs cleaning.

Don't bother with buying the carb cleaner in the paint can/pail at autozone, although having the pail and the corresponding small parts tray is nice. Instead get a large deal of acetone. You simply need to break the carb down removing the gaskets under the venturis and stuff and then soak the parts including the main body. I usually let it soak over night to boil all the dirt and what not out of it. The one thing you need to watch out for is the acetone evaporating.

A friend swears by mineral spirits like brush cleaner and you could use that as well. It is cheaper than acetone.

I usually also get a can of carb cleaner to blow out the passages in the carb with.

Good luck!!
