Serious carb question answered!

Ok now this is strange.
I removed the carb to look inside it, and as i said it's from a 79 corvette.
well, i cleaned it up and put it back on. then i noticed when i tried to start the truck my "pink" wire behind the distributor would catch on fire. Until it finally burned in two.

Well, it's obvious the distributor was wired in bad (as i said in previous post a wire going to "bat" was just shoved up there)
so per instruction on "points to hei" thread, I snipped old "bat" wire and also the wire that ran to the starter.Then ran a 12 volt inline fused wire from "ign unfused" to "bat" and lo and behold problem gone.
truck now runs perfect again.
It seems all this carburator bogging was somehow due to the connection to the distributor.
If someone can explain this "lack" of power or dying in "third gear" because of the bad disributor wiring i'd love to hear it.



You GUYS are something else, it's like having 10 buddies standing around my truck offering suggestions. Eventually it gets figured out. MUch appreciated.

If you didn't have a full 12v going to the HEI then you had an extremely weak fire especially if you gapped the plugs out to .045 like you should. Opening the 4bbl or even just 3/4 throttle would "saturate" the plugs. 3rd gear would put the biggest strain on the engine so a weak fire wouldn't keep your combustion strong enough to keep the engine running.
