The warmer the engine became, the more it lost power eventually down to almost nothing. I tried adjusting the low and high speed adjustments and made things worse.<br /><br />What steps should I take to make this engine run? It is very clean. My novice guess is the gas that was in it when I bought it was old and made a mess of the carb.
