Hi Carl and thanks. I contacted Paul and I will ship out the carbs to him in a week or so for rebuild. Once I put the carbs back on I will try out the bike again. Carl and others on this forum are just great! I am thankful to be here. The tank needs to be re-done on the inside and I agree with Paul that the tank is a cause of some problems and needs to be cleaned before looking into the engine. The bike starts and idles ok but has been sitting for a long time so I have not run it for more than a few minutes due to some corrosion in the tank. The oil is at level and clean. I will reach out to Don tomorrow. Thanks Carl for your help! David
