[QUOTE="john_bilbrey, post: 704571, member: 40519"] I have an '03 220 w/ no airbox lid and a FMF Powercore II silencer. Stock pipe for now. Can't get this girl jetted properly. Dad and I wore the screws on the carb out yesterday and the day before trying different things (not to mention two trips to town for various jets). Anyway, here's the skinny: Stock was 145 main, 42 pilot, 1173 (stock) needle in the middle clip position. Very rich as you can imagine, had a bad case of the blubbers throughout range but roll-on was ok. Tried recommended settings from here (stock main, pilot, raise clip one notch) - still rich. Went with recommendations from local dealer (135 main, 38 pilot, needle in various positions) - very crisp, ran like a champ mid to top, but from off idle I wick it WO it would bog (WAHH, then die). Borderline lean and had a serious problem off idle. Tried stock 42 pilot with needle in various positions; still bad bog off idle - unrideable. Went to a 140 main, 42 pilot, needle in various positions. Now, borderline rich still with off idle troubles. What to now? Here's my question - am I rich or lean off idle causing the bog? We've litteraly worn the screws on the carb out making changes, with no luck. I believe that the 140 main will be OK, but what about the pilot and/or needle position? Seems like anything other than the stock setup was causing the off idle problems. Any ideas on where to go now? We also tried all above mentioned setups with air screw in various positions. [/QUOTE]
