Hello all

@ Desert1957 It is a gilmer belt drive made by procomp.

As for my truck I have fresh gas, and the miss at idle is gone but when warm and driving down the road anytime I get around 1500-1700 it acts like it has a miss but you hear no change in the exhaust note.... It feels like this:
vroooooommmmmmmm..uga(fraction of a second)...vrooooommmmmmm.uga-uga....vrooooommmmm...once over 1700 It goes away, Buddy of mine says its a lean surge, why would it only do it in that rpm range? I am breaking down the carb and rebuilding it tomorrow... my only guess is whatever clogged the air bleeds may have clogged one of the air bleeds in the primaries this in turn gives enough fuel for idle?!..but not part throttle

Once I find the dang Gremlin that lives in my truck...Im taping him to the belt and letting the fan take care of the rest of him @ 5000 rpm
