Briggs 31N807 0440. Customer insisted that the cam was bad. He'd gotten that from a reputable mower shop in town. Said the ONLY way to get it to turn over enough to start it, was to jump it off his pick up. He said the valves had been adjusted. I know the owner of the other mower shop, and have no reason to doubt their work, at all.
Before I started on it, I did check the battery, and it was weak. But he told me that the other shop used a new battery and it still wouldn't turn over all the way.
So, I took the cam out and found that the compression release was still in tact. THE only difference between that and the new one I had, was the weight on the old compression release wasn't exactly square. It almost look like it has been rubbing on something. But, I didn't see anything that could even come close to touching it. Much less, rub it down that far.
So I called the customer, and he said to put that cam back in it.
Long story short, It acts just like the compression release is bad on the cam. But, the cam is fine. I checked the lobes with a set of calipers. And got 1.23 on both (IIRC) Which was the same on the new cam I had.
Battery is week. Charging it now.
Oh, also, I put on a good used starter. (Easier than changing the gears on the old one. That also did not fix the problem.
