Flooding?
« on: April 24, 2017, 02:29:35 PM »
Hello everyone, I have a 1977 corvette. I've rebuilt the engine and the carb was completely fine before taking it off. I got a generic rebuild kit from carbkitsource, and rebuilt the carb. When finally starting the engine, the carb was leaking fuel out the sides between the baseplate and main body of the carb. The idle was also very rough, and wouldn't really hold and stall out. I took off the carb and rebuilt the carb to Cliff's recommendations based on the first recipe. Now it doesn't leak out the sides, but rather sprays fuel in a fine mist up out the top from the primary flap. Really lost here.

My only guesses are too much fuel pressure. I didn't change the fuel pump, but I did throw in a new pump pushrod and cam. Cam is https://www.summitracing.com/parts/cca-12-674-4

I believe it's around 9.5-10:1 compression. Any idea whats going on??

First problem is low quality parts.

I'd start there and install one of our SR kits.  It will have the correct parts and more complete than the "generic" kit.  Set the new float to the factory specifications.

It would also help to know the engine specifications, to make sure the carb is correctly set-up for what you are doing.....Cliff
