[QUOTE="Rivethead242, post: 70331, member: 549"] James, thanks for posting that jetting link. I definitely know it is a jetting issue after reading that article. I've got my cheat sheet, testing will commence tomorrow, which should at least give me a base to work around with the current jets I have. Only thing it doesn't discuss is how much of a difference will each step up or down for jetting size make? Ill be sure to post up before I start ordering "test" jets. Preliminary brain testing time. The 55 pilot I have in (manual states 52 for sea level->5k, 50 for 5k->10k). This would explain my "bogging" throttle response and rough idle (combined with air screw). My 185 currently in (manual states 175 sea->1k, 172 1k->2.5k, 170 2.5k->5k, 165 5k->10k) would explain the fouled plug last time at LPNF (however, I never get fouled plugs in lower elevation(1k-3k)) as well as the exhaust spooge. Now, how do pipes/exhaust affect jetting? Is there a general rule of thumb to follow in regards to jetting with certain pipes/exhaust ,requiring oversize jetting (or something along those lines...)?
