third most common is the HSH is a little lean..richen the HSn a touch
4th most common is your plug is too hot...try a cooler plug
5th most common is the pipe is too restrictive, install a better flowing pipe..
Yeah i could see that, i was assuming the linkage was not an issue, but thats the first thing to check as any other adjustments will not matter until that is addressed. Personally i use a rubber band to help the throttle close.
