I think we need to know if the smoke is coming from the muffler or is the mower smoking belts etc. Can you mow once the blades are engaged? Maybe you could get someone to watch the muffler outlet as you engage the blades. If you can mow I suspect that is where the smoke will be coming from.

Yes I can mow the lawn.
So it may be that I am getting oil on or in the
muffler.
I will check out the ohv cover tomorrow.

It is not normal for any 4-cycle gas engine to emit oil smoke under the load it was designed for. This generally would indicate the wrong oil, too much oil, a worn engine or a defect in engine assembly. Running too rich for extended periods can cause oil smoke by prematurely wearing out the piston, rings and cylinder.

Have you checked out the deck to make sure all the bearings, belts, pulleys are OK and everything spins easily by hand (of course, with engine off)? Just because you can mow doesn't mean the deck is necessarily in order.

I put the mower on the lift and saw
that the underneath of the frame had
an even coating of old oil and dandelion fuzz.
The muffler was clean in and out.
The mower belt was outside one of the
hold in tensions and when operating
would tighten on the rod.
Therefor the blue oil smoke
and the hint smell of rubber.
It seems to be working now....
