Not a mm but a lawnmower engine nonetheless. I bought a mint john degree riding mower that had set up for a couple yrs that a buddy didn't use. Probably only used a couple seasons. Anyway when he brought it over it smoked like a mother. It resembled a dry ice machine at the local disco. Told him I couldn't buy it so he took it and got it serviced. The mower shop said likely a fuel issue due to setting up and the smoke was white. So he brought it back and it gives off just a hint of smoke at startup and goes away. If it's sets and idles tho it will do it a little then. So I used it maybe 6-8x. I checked the oil yesterday before using and it barely even hit the stick. Starts and runs great but I need to solve this issue before I burn the bastard up. It's a 15hp motor. Any help would be appreciated.

my guess is its burning oil from your discription!

sounds like it needs a new set of rings, Charley. Did you check the oil when you acquired it and was it full?

Yeah when he took it in they flushed the fuel lines, new gas and gas line, oil change..etc. That something I could limp through summer with and keep an eye on the oil or does it need to be done pronto?

If it is INDEED consuming oil , just check the levels each time you mow. is it a Briggs motor on it?

Just keep oil in it and run it. That's what most n1ggers do with their cars

if its burning oil it probably needs a valve job.

is the smoke bluish white?

That's a good sign. It means you still have oil. When it stops smoking,worry

If it sat for a while and has horizontal cylinders it could have had a little moisture in there which will leave a slight rust groove in the cylinder which the rings can't totally seal. It will run great and foul plugs a little more as long as you keep oil in it. Maybe switch to a heavier oil or start adding STP.
