    It's probably smoking due to peer pressure. What grade is it in?

    the smoking is probebly caused by a dirty old carb. if it sat for that long, I owuld take the carb apart and clean it up. modern fuels after abotu 1-2 months tend to start varnishing up and thic an cause things to run bad. white smoke is an indication of water int he system. did you leve it outside? maybe water got into the fuel system. also if the fuel went bad it could cause the same issues, again, take the carb off, clean it and put fresh fuel in the thank. this would be my first start along with a new plug for good measures.

    smoke motor

    wow

    did it sit in the sun shade sun shade like condensation in the gas tank?
    and then emulsified the moisture with some new alcohol gas.

    That alcohol acts like the additive 'heet' and can 'burn ' the water gas
    if the rings did get stuck, I'd imagine some mystery oil in the cyl, spin it and let it sit, do compression check and run it the way they love to run..with slight attitude.

    if somethng serious is wrong, it prob wont make it worse.

    Unfortunately, because it is an old ATC, the death panel, er, I mean the governmental efficiency board has decided to give it standard octane gas and make no repairs. Let the ATC rot, a newer quad can use the parts that would have gone to it.
