Don't switch to cent clutch, unless u want to go really slow, not climb hills, or burn out the clutch. Keep/repair/clean or replace parts on the torque converter

The reason I was thinking about switching to the clutch was because my daughter was riding her gocart and she brought it back with about 8 inches of the belt damaged. Prior to the belt getting damaged she told me that when she would accelerate from a stop and that it would be slipping and then it would Jump when it engaged. She said that she was trying to go over a small curb ( about 5inches high ) and it started slipping. I thought if I changed it over to a clutch that it might give it more torque and possibly a little more speed. If anybody knows how to correct this let me know also if anyone knows how to tweak it out that would be great. It has a 6hp Powersport Techumsah engine. Thanks

A cent clutch will generally give it a lot less speed, and a lot less torque. Post pictures of the torque converter. You will need to inspect/clean it. There is a sticky in the engines and clutches section "maintaining your torque converter"

Trying to mount a curb will make the belt slip, because the wheels are just not able to turn. I bet that if she hadn't tried to jump the curb the belt would have been OK.

I would also recommend looking at the sticky and cleaning the clutch. You could post pics of it and we could help you out

5" inches is NOT a small curb, that's a big one for go kart wheels (even 18" ones)
for small front wheels (10") it's like hitting a wall as you could easily imagine ;)

and for 18" wheels it's a 32.6° (64%) inclination

even with a lightweight fullsuspended kart (~150kg incl driver) that's 800 Newton of force or 175Nm of torque.

With a series 30 TC and let's say a 5HP engine you still need to gear around 7:1 (6.6:1) to make that happen.
And only if you can keep the engine at it's max torque, and a fully engaged driver.

Any halfhearted attempt will ruin the belt in an instant (whom do I tell :D).

So, advice your daughter to stay away from 5" curbs the next time...

or, let us know all the details of your kart,engine, driver and wheels,
that way we can play with the numbers and maybe find a viable solution to climb such curbs in the future :D
