I didn't take it off the first time, but I did this afternoon. I checked the throttle shaft for wear - a bit loose but not too bad. The pump lever/rod was not adjusted properly. When the throttle was closed the pump was not fully seated. I am wondering if that was holding the throttle plate open. I bent the nail that is being used as the rod and the action seems pretty good. I had to run an errand, but it is all back together now so I will give it a try in afew minutes. Thanks for the help Jim and John.
