it runs really great, new motor built by tom at fe specialties, especially due to switching to the 750 with smaller jets. it did have a 850 on it. the egt's got a little higher with the #73 jets all the way around and 750cfm. i was a little concerned about that, but water temp stayed about 180-190'. we also added a power valve to the secondaries.

the idle is strange, being that air mixture screws so close to seated. demon recomends 1-1 1/2 turn out. its almost seated as is now. now after reading the vacuum that is 4"-12", i'm wondering if the power valves are open during idle, not sure if that is possible. the valves are probably 6.5's. wouldnt they be open if idle vac is 4"-12"???? thanks for your help...
