340 yahmaha enticer

I recently acquired my mothers old enticer. It has sat for years, I had a buddy of mine go through it to see if it would run. We got it going but my dad said I should try to find out if that model ever had problems with a green build up in the carburetor from sitting. He said on a exciter that he had, had that problem and it burned a hole in the piston. Like I said it started up but it is smoking pretty bad. Might be the little bit of old gas that was at the bottom of the tank. Since it was given to me and i have no money in it i'd like to take my dads suggestion and find out. just using it to ride a little in the yard with the kids. Any thought or suggestion would be great.

I have yet to see an oil injected engine that doesn't gum up after storage, especially if your 340 still has the original B38 butterfly carb!

If the oil system isn't flushed at the end of a season it will certainly gum up. Normally, smoke is a good thing (blue smoke anyway) that may just be extra oil being injected. Piston burn comes from a lean air/fuel condition. With 2 stroke oil slightly raising the octane rating of the fuel used, I have seen those 440s burn pistons from clogged oilers, though usually just before bearing / cylinder damage occurs from lack of oiling!

Make sure you clean the carb and service the oil system yearly & you shouldn't have any problems.
