I just did a winter tare down and now I'm ready to start tuning again the problems are wot it bogs down so I start adjusting and then it stalls everytime I make a adjustment, Its about 40*F out and I'm using 20% and a mc-8 plug the only 2 things I can think of is I need a HOT plug or I don't think and hope not have a air leak but i really didnt do much to the engine just cleaned the out side and put a new 1-way in and did seal that back up so I'm kinda stumpped.
