It could be running too rich or the ignition timing could be way off.

Sounds like you could possibly have a bent or stuck exhaust valve. I would reccomend taking a look at the spark plugs and see if they are burnt up, a whitish color, or fouledmout from to much fuel, they will be covered in black soot from running to rich.
