so my behemoth will idle fine, but i get on the gas and it'll stall out..ill get a video of it tomorrow after i re-hook up my tech..so i can get a video of the RPM's

if i can keep it from stalling out, it only revs up to about 3500RPM and stays there..it wont willingly go higher unless i floor the gas where it'll rev up to who knows what..and i don't know how to adjust my holly 4 barrel to make the fuel/air mix richer..i think im running too lean...

 

I know that there's supposedly an idle mixture screw towards the front passenger side of the base of the carb, and from what I understand it may be plugged and need drilled out if it's never been messed with. these scans are all I have on the 4180, hopefully they help some. parts #'s 83,84, and 85 in the exploded view show the idle mixture screw.

 

i found 2 screws on the front of the carb..turned them in 1..and the truck refused to run..at all...so i turned them out 3.5 turns each. and now it runs like a charm..at least in idle..i don't have enough gas to run down the road lol
