Well thank you Commander for you advice. I'll get to those points tomarrow and let you know how it goes.
Much appreciated.

Thanks again for the info on the adjusting screws. However, I found another screw that I can't figure out. Here is a picture of it. It is a very tiny screw sitting just behind the carburator, behind the nut that attatches the carb. Could this be an air adjustment valve screw?

Thanks again Commander Scott.

Think I finally found the culprit. I checked the spark (like you told me to do days ago with a nail) and found one cylinder wasn't getting any spark. Removed the coil and look what I found. It looks like a leaky coil to me, but it looks waxy, like brown wax. I imagine it's bad and will now seek another. Thanks again to all.

I put a used coil and condensor that I picked up on ebay and it runs like a champ now. Thanks to everybody for your help. It was just what I needed to get me through this one.
