got my jet kit today and was wondering if i need to install the thick o-ring on the throttle linkage? i already have the R&D power bowl with the stronger spring and i am thinking this is not necessary. anyone know?
I had the same question. I called James Dean himself and he told me that if you have the powerbowl you dont need to install the o-ring. The sping in that takes care of it. Good luck, there worth every penny
