Okay so I bought a GP MX3 from a friend that now has four wheelers and stuff for only 100 bucks. It was in his shed for the past few years so it is in good condition.. I cleaned it up and got it running good. I decided to buy some stiff online from pocketbikeparts (grips, rocket key, carbon fiber reed). I put the grips on, managed to get the reed on, but the rocket key isn't fitting. It seems like it will be able to fit with just a bit of grindIng on the edges but it was frustrating at the time so I just decided to put the original woodruff key back on. Once I had it on I reattached the flywheel, put the cover back on and cranked her up, but it wouldn't start. I have been taking it off and putting back on and checking it bit it still can't seem to start. It is getting fuel because the spark plug keeps getting wet from trying to start it. So I decided to taking the original key off and seeIng if it would start without it but it still wouldn't start. It is getting a spark, and getting gas, and I keeping tightening the bolt holding the flywheel and loosening it to see if that's the problem but nothing is working. Sorry for the LONG essay, I just want to explaIn everything In detail so y'all can be able to help me out more.
