this is a 125cc atv.\
owners said the chain came off and after they put ti back on,it wouldn't start. as u can see,it busted the chain cover and is not on it any more.
but I noticed this has a prong that my others don't have.(it is circled in blue).what is it for?
and if anyone sees any other issues I might need to check,please,let me know. if I can get it going,i may give it away to someone I know who needs it for their kids

 

It looks like a ground clip.

 

Yes,but a ground clip to what? Factory clip or has someone tried to install one hoping to ground something out?

 

Looks more like a bracket to hold something in that hole behind it. Looks a bit like where a speedo drive pickup would go.

As for the non starting, check if you have a spark by removing the plug re-fitting the HT lead and laying the plug on the engine. If you have a spark, clean the carb out, if you haven't a spark, try a new plug then check wiring etc, as in the instructions on this forum.

 

must be for something else, didn't affect the starting problems,it runs now.

 

that little back plug under the clip/hole goes in their. clip holds it in place it may be the neutral safety switch.
