jester... could you explain more regarding the valves after cleaning the fuel system? I ran a can in my tank and haven't yet experienced any problems. Should I be prepared to? This was about two tanks ago.
YOu may or may not have to adjust your valves. It just depends on how much carbon you had on the valves themselves. If the carbon and other junk is not taking up the space where the valve meets the head then you will hear clatter and an adjustment is in order.
