I bought this four wheeler to restore. I’ve replaced (all new parts) starter, solenoid, battery, carb, front and rear brakes and cables, reverse cable, all rear bearings and seals (even swing arm), coil, spark plug & wire… even a new seat… lol. It was running fine with the new carb, etc. when it went into my garage and I broke it all down to fix the brakes and bearings many issues. When I finally got it all done (over the course of 4-5 months), I started it and it seemed ok. Then, it died as soon as I touched the throttle… and won’t start back, even with starting fluid! I put a new CDI box on it… nothing. I checked for spark and it had it. What else am I missing?
