I've got the engine running pretty well. I found that I had a weak spark, so I tested the Electronic Ignition Module and it was way out of spec. I got a new one for $3.99 on Amazon and installed it along with a new plug. I also got some gasket material and replaced the carb gaskets. I was also able to adjust the the governor so it spools up nicely now.
On to the next issue... When I first started it, it revved really high and the PTO came off. I set it aside until I could get a new bolt and spring washer. I was picking up apples off the ground the other day and lo and behold, there was the bolt and washer!!! I have yet to install it back on the engine. So my question, When I put the mower in gear, the drive belt doesn't turn. Does that have something to do with the PTO not being attached?
