I have a carftsman 21.5 riding lawn mower about 8 years old. the problem i have is the left hand side burns real nice and hot on the right side it floods out and cold i checked the coil it seems to be working fine. any options i switch the plugs and the same thing happens.

Posting the model number of the engine may help.

Did you check for spark AT the plug and did you check for compression on that cylinder?

At any rate, you're probably contaminating your oil with gasoline.

May be pull the offending valve cover and have a look?

By all means, and $4 to $5, buy a fuel shut-off valve and install it in the fuel line. Then have the carb rebuilt.
