I got a $20 bike that I cannot get firing it is a 79 ds125 which was the trail version of the TS125's which were streetable. I looked everywhere for a manual, but to no avail. Why is that everyone keeps telling me that 2-strokes are easy. I've been tearing down 4-strokes since the late 80's and have always gotten them going every one I touched. I can't seem yo wrap my brain around the concept I guess. Had spark, but no gas, now no spark and gas running all over the ground. I will be pulling the carb to clean/refurbish. I mostly need help diagnosing the electrical side of it. This is a no battery bike and I don't know where to start.
