Default Buy and Air?fuel meter like LM-1

Bernica If you are having a little stumble in this rpm range, it's in the area of where the primary jets are maxed out and the mains are coming on line. Too be sure about this, an A/F meter is the only way to know for sure. Depending on carb you are running you may need to change the acceration pump cam to start a little earlier to stop this. Going to a Dyno shop is the best bet at fixing the car correctly and getting the right 12.8-13.2 a/f ratios with the car running. Your floats in the float bowls could be low too. There is too many could be's for this issue. If you are running an MSD system, they are know for having problems too. Rick L.
