I really appreciate all the advice and suggestions. The "O" rings are on order. The "How to Adjust the Carb" info is especially good. More info there than is in the regualar manuals. I tried a new tank and lines and bypassed the pump as per Test Pilot 101. I could get it to idle a little better, but not as good as it should. With the "In" line hooked to a separate tank and the "Out" line that normally runs to the carb into a separate container, the pump will drain that separate tank faster than i can fill it! If that is any indication the pump is probably OK.

When I get the Tower order I will repace O rings and clean the Carb. I am determined to get this thing running right. When I do I post what I found. Thanks again.
