I have an 89 VRO 90 hp , I’ve used it prolly a dozen times , it always idled at 600-700 rpm when muffs were on it, suddenly it wants to idle at 2200 rpm, idling the throttle linkage comes close but does not touch the roller arm on the carbs, the butterfly valves appear fully closed, the primer selanoid hoses appear to be connected and tight .
thanks
