I recently been having the same issue with my 5 port. It was running fine the day before still a little rich since I only had about 3/4 of a gallon through it. The next day I couldn't get it to hold a tune. Once I got it to idle decent, the engine would lean bog. I richend up the HSN until it was sticking out pass flush. I finally returned the needles to factory break-in settings and started over trying to tune. What needles are people using to help correct this issue? I don't want to spend $70.00 to $80.00 on an OS carb. The whole reason I bought this engine was for its cost and performance. Any help with what seems to be a lean bog issue will be appreciated. Thanks
