anyone good with carburetors?

out of the carb..

my little drive home found out the engine refuses to accellerate in 3rd gear no matter the amount i try to accelerate, it grunts for a second then downs to 2nd.

found a new carb for $240, dad said he'd help me out with it and take half..a rebuild kit is $50, so given the time to put the kit in and the assumption I do it all correctly.. $120 isn't bad for a new carb...i'm gonna be choked if that doesn't help at the same time i'll change plugs, wires, rotor and cap too just for benifit of the doubt.

found an extra gallon of syntech lying around today too! woohoo
