[QUOTE="BigTerp, post: 456336, member: 9169"] It definitely runs better in the fall/winter, and I do think hot, humid weather is a factor. Didn't get it out at all last fall/winter to waterfowl hunt (new baby kept me home) so it's been awhile since I've been able to run it in cooler/dryer weather for comparison. I have only run it on 93 octane ethanol fuel (as non-ethanol isn't available locally) at 36:1 gas/oil ratio. I run it 36:1 because it seems to run best at that ratio after it was rebuilt, so I never changed. Maybe I should consider 50:1? Not sure if that would help at all or not? Manual states fuel throttle operating range as 4500-5500. When the hull bottom was pristine (which it is far from now) I was getting in the 5300's for WOT rpm's. [/QUOTE]
