I just put a new throttle on my blaster. The threads where messed up so i put some pins in and bpu calk over then. Whenever i get into mid 2nd and higher it whirs and pops and even quits running. I think their might be some kinda air leake but I was not sure.

 

Caulk? Pins? Gee..... maybe you should have someone that knows what they are doing fix the thread problem. The throttle is the last thing you want to rig up.
