Here's the story.. I've had all sorts of fun performace problems, including missing under throttle, fouling plugs ect. I took off the q jet in favor of an edelbrock. I took off the edelbrock and rebuilt it a week ago. I fired it up this weekend and let it idle, it was idling ok. It finally cut out. I think it might have run out of gas. While it was running I noticed a vaccume leak, and found it was around the carb. I borrowed a vaccume guage so I can tune my idle mix screws precisely and find out what is wrong with this motor. Today I realized that the vaccume leak had happened after I rebuilt the carb, because alot of the little star screws on top of the carb were very loose. I tightened them all up. Problem solved, right? I just threw 2 gallons of premium in the truck and sat there with the key turning over for a LONG time.. giving the starter a few rests of course. The clear fuel filter was full of fuel for quite some time. It won't even try to fire at all right now. So I decided to pull a random plug, half expecting it to be fouled with rich fuel deposits. Well, the plug is bone dry, not really wet with gas, dunno why... but here's another odd thing. It looks like it has been fouled at somepoint with black carbon deposits (man I've gotten used to cleaning those with a wire brush). But it also has a white spot on the electrode, as if its run lean.. its really throwing me for a loop. Anyone got any ideas?
