Hey gang,
If you have a twin cylinder lawnmower that is hard to turn over, take out one plug! Sure, it will run on one plug. Let it warm up some and put it back in and it will turn over about one turn and away it goes. If not take out the other plug and warm up that side. This is the easiest way to get the thing started. Thanks for lookin'.
Compression release on camshaft will not work as it should if valves are out of adjustment. Engine should be cold when adjusting valves. Operators Manual should have valve adjustment specs.
