I have 47.5 hrs on my Simplicity Prestige, 2008 manufacture. Engine was a great running gem with no prior problems!!! Well taken care of machine! Normally, after blade shutoff, engine maintains fast idle. If I turn engine off immediately there is run-on or loud backfire. If I let engine idle from 30sec. to 1 min. minute after blade shutdown, no problems!!
Last week I finished cutting back yard of .75 acre. Shut the mower deck down and shut engine off following at around 1800 rpm. Let engine cool off. Upon restart, blue smoke!! I said OH MY goodness what happened. I've never seen this before on any air-cooled engine. Why did engine go from beautiful to oil burner?
