I got a JD 210 where the PO had sitting out side for years just sitting.
I got it running and it starts and runs great, but it does smoke (burning oil smell)
for around 10 minutes after each time I start it ( after it cools down)
I think the rings are not free as they should be - cause it to smoke
I did check the valve clearance and they were now the money be the Kohler
If I am right - what is the best way without replacing the rings and valve job.
I would like not to take it apart at this time
would Marvels Mystery Oil or some other additive help?
