I have a TaoTao 125 with the forward neutral and reverse lever it will go into reverse and move it will go into neutral but when I put it into forward or drive it does not move I was told it may be the sprocket on the output shaft but that was from the person I bought it from but when you put it into forward or into gear to drive you can hear it click but it doesn't move but like I said it will go into reverse and I can drive it backwards as much as I want any ideas of what I could do would be appreciated

 

If their is a shift linkage on the machine try disconnecting the lever and shifting into forward by hand. If its a solid shift arm with no adjustment make sure its not rubbing on something. Other than that it will be a internal problem and you will have to dig into it

 

I'm not familiar with these the shift arm came off but it attaches to a know coming from underneath it it shifts into reverse fine and back to neutral fine and you can feel it move forward to put it in forward but it won't move. I was told something about a sprocket by the person. I bought it from

 

I'm having a problem with mine popping out of drive as your going.
