are u getting any leakage around your carby boot on the slide ? a pin hole will do it !
i & others have found this after going through what u have !
as rex said replace your needle seals with the nitrile ones & your carby crankcase seals aswell
some fuels will gum up if left in the carby for to long, so while you are replacing the needle seals give the carby a good clean out too
what are your exhaust seals like, if old replace them
hope something helps here
