Racing engine
 

this is on a 64 chevy after rebuilding the carb the engine just races at startup. ive tried adjusting the idle and messing with the vacuum advance but nothing. any ideas?

RE: Racing engine
 

What kind of carb/engine are you running?

RE: Racing engine
 

its not my truck, im just doin the work. buts its a 250 with a 2bbl carb on it and i believe the engine is a 79 if that helps any.

What condition is the linkage in??? You might have a slight problem with the floats sticking or something... Time for a rebuild kit...

RE: Racing engine
 

ive already rebuilt it. and rebuilt another one and it did the exact same thing.

RE: Racing engine
 

YOU must be doin sumthing wrong then, are all the needles and adjustments set correctly?

RE: Racing engine
 

can the float being bad a possibility here?

RE: Racing engine
 

I thought you rebuilt it?

RE: Racing engine
 

yes. rebuilt 2.... exactly the way they came apart but with new parts ive never seen anything like this before after rebuilding a carb. ive done it many times so i dont see how i messed it up unless the float is bad but kits dont come with them anymore these days.

Have you chaecked the timing? Maybe there is a vac. leak...
