Belt Grabs

[jganley]

Not sure what car I have, but there is a logo on the nose that says Sprinter also has a molded dump box. This car had an 8 hp Robyn engine that was shot, so I put in a Duromax 18 hp electric start. When I start the car up, all is ok, but just a bit of driving, and the belt grabs only way to stop is to turn off the key. I only use this car in my yard to do gardening and chores. Currently, I have the car up in the air with the belt attached, and when I turn the driving pulley, the belt slides freely on the clutch. Any suggestions, also the clutch is what was on the old engine, and I cannot see any markings. I have included a pic of I do not know it moves with the left tire and spindle is there supposed to be a shock on this.

The clutch is most likely defective, or your engine idle speed is set too high. How about posting photos of your cart plus one of the clutch assembly. I can see that you have posted one picture, but can see no clutch in it.
