    I recently replaced the entire electrical system in my grandson’s 50cc ktm. It wouldn’t run at all before and now the engine will only run backwards. The rear tire actually turns backwards. I’m hoping that someone else has run into this situation before, and can tell me what is causing this to happen. It seems to me, that the ignition is firing after top dead center, instead of before top dead center. How could that happen? Austin Gibson
