I have a 64 GTO and recently sent my original Rochester carbs (tri power) to Holley to have them rebuilt, replated, refurbished, etc. The good thing is that they look great. The bad thing is that after I got them back on the car, I got the car to run (and not well I might add) for about 15 min before it quit. Now when I crank the engine, gas pours out of the bowl vent onto my newly painted engine and it will only run for about 5 seconds before flooding out. My first guess was to (even though I put on a new fuel filter and fresh gas in the tank) take the top off and clean out the bowl and needle and seat valve. I blew everything out with compressed air and there was no visible dirt or the like anywhere. I got it all back together and there is no change. I haven't done anything since except call Holley. They said to send it back and they would fix it which is good. However, I haven't driven the car in 6 months and winter is approaching and I really wnat to take her out for a spin. My only other guess is that the float is out of adjustment but that seems unlikely. My question(s) to the forum is: what is the correct float setting so I can check and adjust it if necessary so I can drive this damn car before the weather hits and I go nuts? If it's not the float, does anybody have any other suggestions before I send it back? Thanks in advance for any help.
