riding mower runs then smokes

I have a craftsman LT 1000 with a 17 hp kohler ohv engine. It will run perfectly for a couple of minutes then start to smoke heavily for a few seconds. It will do this every few minutes. After a few times it will start to knock.

Thanks for any help.

If your oil level is not overfull, and/or smells like gas, then you likely have a blown head gasket.

Post the engine's model and spec numbers for more specific advice..

thanks

What if oil smells like gas or is overfull. Drain it and change oil? Is a gasket blown?

Thanks,

If it's overfull and gassy, the carburetor needs repair because it is leaking fuel into the crankcase. Once the carb is fixed, drain and refill the oil with the proper weight and amount.
