I know you said you had it a TDC but that was the piston you can have that right but the cam be off check your camgear settings too.

Thanks for the reply. I had the piston at TDC and the Cam chain at TDC , and I put the cam in right. The valves are opening and closing at the right time.

Then you should start. if you got fire and you got fuel all timing is correct then you should start.
I can't remember if that has reverse or not if it does check to see if it is in reverse, or bypass the reverse switch. just a thought.
