Heres the deal, Just got a 1969 torino, runs like a rat, actually runs out great but barely will idle, Has headers and a holley 2 BBL, tried a tune up, same, has 125 lbs compression across the board, figured the holley was maybe too fat, replaced it with a autolite 1.08, jetted to
50 in the primary, new carb. Still rough idle, seems like vacuum leak...kinda goes up and down at idle, so put new gaskets on intake to go along with the new gaskets on carb and spacer, capped off all vacuum tee's, tried pvc valve. still rough idle....tried air screws in out up down, no help..advancing the timing helps, but idles like a rat...anything less than 900 rpm it will just die, pulled distributor, has slight wobble at points but not sloppy.....runs great when on the gas pedal, but crappy ratty idle....what next? Timing chain? distributor? HELP- posted
