OK, I appreciate the comments. It is a new plug and battery but we all know how long batteries sit on the shelf. Especially 6 volt. I will try your suggestions and get back to you guys.
I have a new carb. that adjusts fine, points are good, valves are adjusted. When I get to mid throttle, even with no load, it breaks down popping and running rough, no power. Could I have a bad condensor?
