So I have an old Craftsman generator that I got from my Father in law. It is rated at 3500 watts. He said the carb was gummy. I wanted to keep it in the Blazer for extended trail rides or camping, and to run the air compressor or tools or welding machine if needed. I got it running but still think the carb needs work. A guy at work told me he had a generator like mine. His advice helped get mine running after I cleaned the ignition points. My problem is that it won't generate power. This guy told me that you sometimes have to hook the 12 volt charge leads to a battery in order to establish the polarity for the generator. My generator doesn't have 12 volt leads on the panel for battery charging, but I have been hooking a battery to the solenoid with red, and frame with black to electric start it. I think the carb has some plugs in it cuz I can only get it to run smooth at about 1/2 the RPM that I expect it to achieve. When I clean it all really well, that should allow me to adjust it up to full speed, but It should at least have low volts now and does anyone know what I am talking about?
