I have a 84 c-10(STOCK) and am in TX with Tx summers usually about 100+ for a few months, pretty extreme conditions. I am using a rebuilt quadrajet and have tuned it and like where its at, but the fuel in the bowl seems to be heating up and over flowing. After driving for about 30 minutes and shutting off, if I go back to turn it on the engine is flooded. I can also see where fuel has pushed out up around the top of the carb. The float level is as low as the book recommends.
One issue is all the old stock emissions lines. I did not want to remove them even though they were not working and unplugged, everything was there and I wanted to keep it as stock as possible. Well , last night I could not leave it alone anymore , stock or not, it just wasnt helping and was hurting the issue. Having about 20 hoses across the front of the intake was block all air from flowing around the carb.
I have ordered a 1" phenolic spacer for the carb so that should help. I wanted to keep the truck as stock as possible(but thats seems impossible) but I think next will be to remove the steel intake and install a quality alumn. Its a daily driver and stock HP output.
Should I block off the heat cross over in the intake? Anything I am missing? So much for keeping her stock
