350 Moto 4 won't leave first
 

I recently bought a moto 4 that was not running, and needed a new centrifugal clutch. After I put one in and got it running, I couldn't leave first. Or second maybe. I can shift from neutral and go one up, which I just assumed was how this trans was set up, and back to neutral. I can't get any other gears though. Is is possible I put something back together wrong or is there something wrong with the trans?
