Hi Guys,

Toro 22" self propelled mower seems to run fine, but has constant light blue smoke from exhaust...checked oil and it's right on the "Full" mark. I suspect a ring problem, and if this is the case can it be fixed, or is it cheaper to replace the motor?
Thanks for any help. BTW...this just started happening.
 
This is a Briggs and Stratton 190cc motor on a Toro self propelled personal pace mower.

The numbers on the engine are:

7BSXS.1901HV 277315

Hope these are the numbers you need?

Thanks for the help.
