Default Re: Carb issue..! Bogging off the line.

Bog fixed. This combo (331, N91) has 25* of overlap at .050 and very little vacuum at idle.

I brought my LM-2 air fuel meter and took a look at what we had.

Idle bleeds were 70/70 and mixture screws were 1 1/4 turn for idle of 13.5-14.0. Cruise (2000 and below) was around 13.0. Idle bleeds were pretty much right on.

Patrick had 40/40 squirters in it. This combo just needed more fuel.

Took the squirters all the way to 55/55 and it was super responsive but also about 10.0:1 when he mashed the gas. Backed it off to 50/50 and ran out of day light.

No top end pulls so we couldn't see how close the jets were.

The Pro Systems carb is a nice piece and I think we can get Doug's car to go 125-126mph with a little tuning!
