EZ GO Golf Cart Clutch CVT Problem

2003 EZ Go Golf Cart-Clays Car with 350cc Robins Fuji Engine. I am having problems where the cart goes backward and not forward.
I am not sure which clutch is bad, the tranny clutch or the engine clutch. These clutches are extremely expensive. If anyone has experienced this problem and was able to fix it, let me know in the comments below.
