1993 EZGO Gas Golf Cart Only Gets Spark When I Let off Pedal

Ok so it works when I pick it up but I watched it when I go up the hill and it’s like the clutch backs off a little bit and the belt just slips ?

So the engine is running and the belt is just slipping around the clutch - did you install new and correct size belts?
 
I installed the belt that was on it but everything I read is it should only have 1.5 inches of deflection and it has closer to 4” so I’m thinking belt is worn and wrong size belt ?

The way it reads, it appears he put the original back on because the new chinese one didn’t work.
