Hey, im new to the forums and was wondering if someone could help me with my 1969 ts250. First off it has a good spark. I can't get her to run, but i can get her to fire for about half a second every once in a while. I have cleaned out the carb and same problem. I can put some has down the cylinder and it does sometimes do either a loud backfire or a half second fire. I can't even push start her, and i have tryed about 3 times for 200ft at a time. Does anyone know what i could do?
