Default Re: Engine stumbles on acceleration

Bill OH,
I tried regapping the plugs. I thought.025 was a bit tight so I went down to .030”.
I went for a long ride to check it out. To me, it ran OK but I think it ran better at .035”
I filled up the gas tank and added some Marvel Mystery Oil.
Somebody asked the type of plugs I’m using. They are Autolite.
