So here is the story: 66cc (strong compression), No air leaks, NT carb, been having a 4 stroking problem at 3/4 to full throttle. Played with different c-clip settings on the needle didn't solve problem. Picked up some jets from SBP, got a 68, 66, 64 & 62mm jets. Tried the 66mm with every position on the c-clip, still the same. Went to the 64mm and have the c-clip set at the richest setting she got better, any other setting she 4 strokes. So, I know these little engines all have different issues, but with the setup now on the carb (64mm jet & richest c-clip setting), is this normal? I know I need to do a read on the plug.
Has anyone else changed their jets and to what size are you using and setting the c-clip to?
Thanx,
Pete
