Yes Frank the cam is at the limit as far forward as I can bring it. It doesnt look bent. It is not the first one they all seem that way and I have worked on six of them over the last few years. I must be doing something wrong, not understaning something.

Thanks

You won’t really be able to see if the cam is bent unless you compare it to a known good cam. These cams are easily bent backwards, usually when the carb butterfly is seized/corroded. The metal cam follower won’t budge when the throttle is advanced, so the steel cam just bends backwards.
