Hey fellas!! /forums/images/graemlins/1zhelp.gif Well I got her to pass emissions!! Problem now is driveability (sp). 79ish 400 with Q-jet. I rejetted it to high altitude jets and rods, retarded the timing to 14deg. before TDC, and went with ACDelco 45s plugs. When I gas it from a stop under any throttle, it stumbles for a second. And when I floor it, the secondaries just bogggg... Carb been rebuilt, new fuel lines, pump, filters, plugs, wires, cap, intake, and air cleaner. Now what do I need to replace or fix??? /forums/images/graemlins/angryfire.gif I'm runnin true duals, air injection, new cats, and original diesel mufflers. Really disapointed in the crappy performance of this thing. Was kinda hoping the chrome valve covers and air cleaner would make it faster... Guess I should find me some stickers! /forums/images/graemlins/thumb.gif Thanks for the help! Sam Oh, if theres anybody close to me that wants to come over and tune this dang carb, I supply the refreshments!! /forums/images/graemlins/grin.gif Got some home-made wine thats 2 years old and smells like paint thinner!! Adjusted the air valve and no more bogggg!! Oh and fixed the heater too! Think I might have to replace the blower motor cause she don't blow too hard.... Thanks for the help guys!!
