Chuck's problem cub

Fri Dec 31, 2004 10:27 am

Many of you will remember my posting a couple months ago about the neighbors cub I was working on. He had it rebuilt 3 or 4 years ago, and it had never run right, no power, etc. Rather than taking it back he just left it setting out side. when I started checking it I suspicioned the valve timeing was off, and an apparent misprint in one of the service manuals confirmed it. When I got it apart, I found that was not the problem. Weather and health had prevented me from doing anything more until yesterday. I was feeling good and the weather was warm, so I decided to take another look. Found 5 of the valves set quite a bit to tight, and the spark advance was gummed up and not working. Now all I need is some ambition and the help of one of the neighbor boys to get it back together.

Hey John, which service manual had the misprint? I'm getting ready to do that procedure soon on my rebuild and I'd prefer to not have to do it twice. :)

The assembly instruction are correct in all of them, but in the I&T manuals there are instructions on how to check the valve timing with the engine assembled. The error is there, which caussed me to needlessly pull the timing cover. I have 2 of them, and one is correct, and one has an error. I don't have them handy at present, so I can't tell you which one.
