Hi guys, I'm new to this foum. I've got about 900 miles on my 48cc bike. It went about 200 miles like a champ. Then all of a sudden the weirdness that has become worse and worse. It is very difficult to start. It will only start if the kill switch is activated. It runs very poorly, (4cycleing?) If I can catch it just right I then have to push the button again and an IF I am really lucky it might go into a good 2cycle mode. If I don't kill the motor, it will run very nicely until I shut it off again. The thing won't even think about firing unless it gets grounded first. I've spent hours messing with wireing. I got a new magneto and it would not run at all with the new one under any circumstances. Can someone stear me to a fix? Would it be the CDI? I figure as good as it runs when it does start thats not it.
