QT 50 BACK TIRE SPINNING BACKMARDS

Well I bought a qt 50 yamahopper engine off ebay. I removed oil injection gear and screwed the pump back in. Also since the motor didn't come with CDI I bought one of those cheap 66/80cc bicycle engine 2 wire cdi with coil units. It runs but the tire spins backwards. I have another 6 wire AC racing 4 stroke cdi for a gy6 chinese scooter. Does anyone know if that would fix it or have any suggestions please

Maybe time it to fire before TDC and spin the motor opposite of what you been doing ?

Tweaker trash /

It’s a good thing it doesn’t run

Re: QT 50 BACK TIRE SPINNING BACKMARDS

most 2 stroke motors will run backwards if the timing is off
