Me and the onan got to know each other pretty well over the last couple of weeks. I started to decarb the heads and pistons and do a valve job while I was in there. Well the valve keepers decided to fall into a hole so I had to go further in the engine than i originally ment to but I had fun. I havent been this far into an engine in 20 years so I had to brush up on a few things. Anyway i got it all put back together and it does run better. I am still having troubles with the DD13 carb but thats for anothe thread. I have succesfully mowed the yard with the old girl and she does great. I have to use 1/3-1/2 choke but it runs smooth and has governer response just as if the choke wasnt on. So far thats the only problem i have that has not been fixed properly.

Inside I found two valves that had damage to their sealing faces. The seats were good so I just "power lapped" them until the damage was gone. I had to re adjust the valves after this. I rechecked my timing and made sure everything was torqued properly. All my gaskets came from "Garys place". I am happy with all of them except for the intake gaskets. They are made of some very fiborus material that doesnt like to be reused. Luckily another set came with the carb kit that I had.

I also picked up and installed a voltage regulator/rectifier so now my battery is getting charged. I also got an ammeter installed.

Looks like an air filter housing screw got under that valve for sure! No way that could have ran right. Good thing you got into her! Now even though a keeper fell into that hole, aren't ya glad I coaxed you into a valve job?:D
