White smoke

What does "white" smoke (or light blue smoke) indicate thats wrong? I've always been told "black" smoke indicates an over-rich carburetor condition.

Usually white or light blue smoke is oil beining burnt. How is you're oil level. Make sure it's not over-full. If it's O.K, does it smell like gas?? If so, a carb overhaul may be needed. Let us know what you find, Roger.

Thanks for the reply Rodger. A friend of mine has a Kubota that was doing just that. He said that he changed oil and it corrected the problem. I'm guessing that it was probably over filled.

Generally, black smoke=rich fuel condition; blue smoke=oil burning (reason: to be determined) and; white smoke=fuel diluting the crankcase oil (reason: most likely a dirty/varnished carburetor allowing fuel to dump).
