I switched the cam to the other mounting hole and it helped.... I can run at 65+ fine..and 35-45 ok too...Plugs were grey/brown...I had already timed to 12deg. and switched from the vac port under the front of the carb to the ported one up on the top by the bowl plug...now the total advance is @36...not 46...oooops. It seems as if it's not enough fuel from the acc. pump off idle before there is enough air flow through the carb...Should I get a cam assortment kit first to try?
