OK, so my grandson's quad has a Honda 110 cc engine. when I press the start button the solenoid comes in and I have power through to the starter but the starter doesn't spin. After playing with it a few times I did get it to turn over once for a few seconds until I realized there was no gas in the tank so I filled it and tried again but, once again it would not crank. I removed the two screws holding the starter to the block but the starter motor will not pull free. It backed off about 1/4 " but seems to be hanging up on something inside - is there a trick to this?
