My neighbor gave me this push mower. He told me that it ran fine when he parked it, but that it had sat for about 2 years…outdoors!
He told me that he believed all it needed was a carb diaphragm and gasket and it should be fine…ohhh, and that he had messed with the ground wire on the back of the engine. Well, I ran a cylinder leak down test and discovered what I thought were bad valves. Turns out, it was just a bad head gasket. All in all, I have about $50 in new parts for this. But, it runs good now.
