Still had to continually prime for2 minutes before it would stay running. At that point putting finger over primer bulb hole would cause to falter to point of stopping. When rpm drops with falter the governor opens the throttle but it continues to stop. After 5 minutes of running then putting finger over primer bulb hole causes a slight drop in rpm but it stays running. I'm using original o ring on the intake pipe. Can't think of anything else except checking intake valve clearance. I do have another similar mower just left at dumpster. I guess I could see if I can get it to run and then try it's carb on the problem engine.
