Friend bought a Farmall A that blew smoke rings when idling.Oil was seeping past the spark plug gaskets.A compression check showed 100 lb on all cylinders,I think so much oil was getting past the rings it gave the high readings.The oil was clean but down a pint.I added a pint of MMO to the crankcase.I used the tractor to rake some hay.It put out a steady plume of blue smoke while working and blew smoke rings at idle.It fouled spark plugs often.Oil has to be added every time it was used.Friend used it for garden work last summer.His son in law changed the oil this spring and the smoking backed off.I just put a new bail on the sediment bowl yesterday and noticed smoking had stopped.It doesnt use oil now.The engine sounds better now.I suspect the oil rings were stuck in the grooves.MMO is more solvent than oil so I wouldnt use it unless an engine was on its last legs.ATF probably would have done the same thing.MMO caused a gas shut off valve to bind up so tight that a big screw driver had to be used to open and close it in my 600.It took full year before I could operate the valve by hand.
