proform carbs?
running a 750 race series proform, love it,runs hard, starts easy,idling as nice as a 340 with a solid roller can....responds nicely to adjustments also
only problem i have found is that the idlemetering screws have a bad habbit of adjusting them selves but i fixed that with just a small drip of paint after adjusting them, a friend of mina almost lost his adjustmentscrews before he found a way of locking them..
