Bad piston rings, oil level is too high, check the oil level and adjust
No you can't use a golf cart mower on a lawn mower. You have to find a muffler that matches the make and model of the lawn mower.

Oil burning
its probably burning oil, if the smoke is white. if the smoke is black, it means its running rich. if the smoke is white, you have serious internal engine problems
white smoke comes out when you use wrong gAS, Like if itsays only UNLEADED and you put diesel,,then you will see white clouds.

It is need of a service.
to much oil in unit or it was tilted and oilleaked out of the case and the extra is being burned off
One reason that a lawn mower may begin to smoke is that the oil chamber is too full. Spark plugs that have burnt oil and are not cleaned can create smoke and other exhaust issues.
its burning oil :(
A sheared flywheel key (advanced timing) will often cause a red hot muffler. This happens when the mower blade hits a stump, rock, etc.
Probably to much oil in the crank case. Otherwise mixture control on carb. is off
