[QUOTE="2stroke, post: 1380814, member: 25668"] plus one on lowering the compression, but an easier way to do that is add a second head gasket. No machining involved. I would start moving the clip down slot by slot...that will affect the top end...if you r top end is bogging, its starving for fuel...a lower clip will mean a higher needle position at half throttle, and so more fuel. that may also help the starting, since it will richen it up throughout the range. Seriously, put the needle half way and try that, and move further down if no results. [/QUOTE]
