well, i know my choke is fine, but my air filter may need a little work, because it is slightly singed somehow... i think that it might have backfired through the carbeurator... i think that it might be overfueling, because when i took off the airfilter, it did blow out ALOT of white smoke... after that i tryed using some carbeurator cleaner, but it had no effect.
i do beleive that it is... sorry.
