I just fully rebuilt a 3310-4 that came on the 34 coupe we bought. Car sat for 7 years so I figured tearing it down and rebuilding it completely was a good idea. After all I have rebuilt a few holleys and they all turned out great before. We got the car running before rebuilding the carb. It ran reasonable but I just had to rebuild the carb because surely after sitting 7 years it should need rebuilt right?
WRONG
I messed something up and cant figure out what it is. It is so rich it wont run unless I hold the pedal and it is shimmy and shaking. I jump out real quick to try and see fuel dribbling or something and the primary butterflies are wet but I don't see any fuel dripping so I open the blades and there is fuel pooling up in the performer intake. It was also smoking like a freight train (literally).
So here is what I did
Disassemble and clean everything spotless
Blew 120psi compressed air through every single passage including the air bleeds
Reassemble with all new gaskets, needle and seats, new 6.5pv, vacuum secondary diaphram, adjust transition slot to a square and set idle mixture screws at 1 1/4 turns out
Install and reconnect all vacuum lines then set the floats. I have double and triple checked the float level and it is spot on. I have pulled both needle and seats to check for dirt but they are clean.
Problem still persists and I am at a loss?
