It runs better with the 56. Shoud I have the 8.5 powervalve in cus of the hi vacuum at idle. I have the 6.5 in now. Im running pink cam 2 hole an 3rd in cam. And 31 nozzle. And it runs good but I think it should be better.
In beginning I ran 51 main jet dual stage pover valve 5/15
31 nozle orange cam. Ran good but had a lean spot shifting in to 3rd gear always. And if I didnt have the accelerating pump adj perfict it would run terrible. Thats when I took to dyno and they just over jetted it.
Ill l;ook in to locking the secondarys. The missing screw hole was that letting gas into a area?
