1965 421 Tri-power
What is the easiest way to tell if my tri-power is running rich at idle. I have been suspecting it is for a while now. I do smell something odd while at idle. If it is do I correct by adjusting the idle screws or do I need to change out something else.
THe tripower was restored several years ago by Mike Wasson. I put it in a 421 that Butler Performance bored and stroked to 453. They put a comp roller cam in and they got 491 HP out of it.
