i believe the popping is from the exhaust, i can feel it in my feet. but it is kinda hard to see the carb while driving. and when my dad was following my once (incase i broke down) he could hear it and it puffed out smoke everytime it popped.

i'll try the slow reving in park and see what happens.

yes thats a nice street and strip cam......
so ur saying the popping is from the exhause not the carb,,,,please try this in park,,,and let me no what happens,,also im thinking you may have some adjustment issues on the valves
(exhaust valves,,,,,)im wondering how did u adjust them ,,
