Working on a Toro Model: 75754, Engine Model 139-0602
The complaints and observations are: when deck is engaged the engine "bogs" down almost to a stop but will regain rpm. Low power. Exhaust smoke. Oil in muffler outlet.
I did a compression test on both cylinders: both tested out 150-160 psi. Owner says he replaced carb?, new oil/filter. He says he has noticed slow increase in sump oil level in a 6+ month time period.(not sure if this was before or after new carb was installed.)
My next steps are to remove the flywheel cover to be sure the engine breather hose is intact and not leaking on the way to the fuel pump....,
I'd appreciate any and all suggestions...
Thanks in advance,

It's not...all the time. I checked valve clearance on both cylinders....tight, zero clearance(set at .004"). The suspect cylinder does eventually fire (checked with a heat gun on the exhaust pipes) then dies in less than 30 seconds. The spark is very weak.
