Re: oily spark plug
Hey Manny, a rich mixture will leave the plug with black soot, and it will be dry. Oil fouling is a wet, oily deposit. Oil in the combustion will also cause blue exhaust, while a rich mixture makes it black.
Check your compression. If it's low, and the plug is getting oil fouling, your rings are probably worn.
There should only be 1 qt of oil in the crankcase. is the inside of your air cleaner box clean?
How does the cart run with a new plug?
