OK, what the heck am I doing wrong?

[Bobby Zlatkin]

OK, thanks to you guys, I finally get it.

I did move the cam 10 degs. but the degree wheel is attached to the crank, not the cam, and that's where I was reading 20 degs.

It finally hit me this morning when I was on my lawn tractor mulching leaves. Can't believe I didn't/couldn't see it sooner. The cam will come out and go back to the manufacturer who is anxious to make the correction and send it back.

Thanks again.

I'm not really stupid, just dumb.
