Re: Correct Piston..Finally!
I haven't checked the points yet, but from I have seen so far it looks like the cover doesn't come off as I've seen it in videos. It appears that just the back side or panel comes off. Seems like that wouldn't give you much room to work between the engine and the firewall in front of the battery and tank.

Vivala, check page 18 in the above manual. Some Onan's have a cover in the rear between the battery and the engine. Some have a cover on the top. The rear facing cover comes off with two bolts and the top comes off with a bolt on the top. The top cover type is easier to adjust the points. The rear cover type is a bit harder because of space limitations. It would probably be easier to remove the battery to get the rear cover off.

Not much room there for sure. But I did it on mine. Not so bad once you get the cover off and get a look at it. My cover has a screw in it. Make sure the wire inside is not touching the cover. Won’t start if it is. I had that trouble. Took me a while to find that. I put a piece of thin card board, like a business card, inside the top of the cover to stop that.

I could swear it looks like mine opens differently but I'll have to double check. It's always looked like mine that same cover on it but only the back side came off

Re: Correct Piston..Finally!
@Vivala446 I would recommend that if yours has the back cover you change the condenser while in there . You did have an issue with the ignition switch . If you have really fine sand paper polish the points , I like 400- 600 grit . If there is oil in the point box, clean with brake/parts cleaner and blow dry .
