well guys i have been through and through it, carb apart and back together. floats adjusted, tried diff accelartoin nozzles, on the phone with tech for 2 hours runnin through carb. They said to mail it back because they have no clue what could be the problem sense we ran through everything. I adjusted and readjust my lifters. tried many diff timing settings, all ignition parts r working well. but it Just kind of came to mind that when i installed the 2.02 heads roller rocker arms and cam that I used the supplied springs supplied with the heads and not from comp cam which is where the rockers and cam cam from. Could this be causing my problem?
