back firing
not sure if its been asked. can't get the search thing to work. but i've had my 7 for about 2 years now, and it started to back fire about 5 months ago. been told it was runing to lean or the air control value went out. but can't seem to figure out why its back firing. so if anyone has any advice i'd greatly appericate it. like to keep my limited on the road.

well a year ago i had the carb rebuilt and a new shutter value put on. previous owner wired it shut for some reason. before i bought it they had a hole new exhaust put on. still in great shape, since i try to avoid bottomin it out. its still just a plain stock engine, intake, carbs, etc. haven't had the funds to mod it. and of course the seasonal tune up.

the whole thing is on pretty tight. takes a little effort to get the wing nut to break. could there be a house that i should check? i've heard that if it back fires a lot. it could cause the engine to need rebuilt. and i diffently don't have the money for that.

haven't done and don't have anyone to teach me. still learnin the trade of do it your own.
i've messed with the mixture screw to see whether it was running lean/rich. i tweaked with it. i'm sitting about 1 and half turns out. it was at 2 and a half. it only seems to back fire when i'm high in rpms and let of the gas to shift up or down. if any of that helps.

If you had a problem with the leading ignitor as stated before the engine would have very little power.
As far as the hoses go, check to make sure they are not cracked and are attached properly to their respective homes.
Wacky,
Are you refeering to the shutter valve?
