Default Re: Jerky Runner

Well I took the old jerky runner out for a drive today. About 2 weeks after the MMO treatment in the cylinders. It started better than it ever did, after warming up (46 degrees around here today) and ran like it should. No jerks and good pickup. So I again would guess that I had a stuck valve or it may have be very sooty spark plugs that cleared up with the MMO. But I am no experts on this type of thing but this is what it seemed like to me.
