The info on mix screw settings is greatly appreciated. :-) I worked in a garage for several years when I was younger and also did small engine work, but I never worked on a 4 bbl before now.
The engine itself was overhaulled three years ago (rings, gaskets, valves, etc.)by a guy who had 20+ years working on GM stuff (Retired GM dealership Mech.). It ran like a champ this Summer and Fall. Normal warm up took about five minutes with the choke doing what its supposed to. The exhaust looked good, no smoke and no signs of running over-rich around the tail pipe.
During this latest "difficult" phase, I haven't been pumping the pedal at all. I've been turning over the engine while standing outside the truck to watch for leaking gas. FWIW, the last time I pulled the carb was right after it puked some gas. The inside of the manifold wasn't soaked, just some gas directly below the carb.
Between us, I think the truck got spoiled after I overhaulled the suspension, installed a new gas tank and sending unit and cleaned/painted the frame. ;-) It now has an attitude that if it throws a tantrum, it knows I'll work on it and not use a sledge hammer or a cutting torch. In other words, the truck is now spoiled. LOL
Anyway, I have new vacc lines and a choke pull off I'm waiting for. Once I get the parts I'll pull the carb again and dis-assemble it just to be sure none of the small tubes, ports, or jets are plugged with crud (I may as well check them again). Likewise, I'll check the number of turns on each mix screw before I take them out for cleaning. At this stage, I'll also pull the plugs and check them for abnormal wear or color but I think the valves and the block are fine. I'll also pull the dipstick and check the oil for signs of gas in the crankcase.
BTW, to all. I truelly appreciate the info you've provided. I'm trying to give as much info about what's been happening so my posts have been a little long. This problem has been frustrating but hopefully it won't be terminal.
