go kart not moving

[JoeZ]

I am working on a MM 80 go kart. Cleaned & lubed clutch. New carb, starts & runs fine. Brakes not locked up. Leak down test good.
But will not go up hill & barely move on flat surface.
I appreciate any help.

does it have a centrifugal clutch or a torque converter to drive ?

It has a centrifugal clutch. The clutch had quite a bit of rust on the pads & backing. I cleaned off the rust & used brake grease on the back side of the pads.

That's probably why it ain't grabbing.....you greased it. The only lube is a drop of oil on the brass center bushing every few weeks.
Use Brakleen and wash out that grease, repeatedly and clean it out spotlessly....... No lube of any sort inside

After I did the above procedure it was the same as before no better no worse. I did put a couple of drops of oil on the brass bushing. The grease was on the back of the pads & after assembly I cleaned it toughly with Brakleen just to make sure no oil or grease was on the contact points. Are you sure about no lube on the backing plate?
