Heavy kart, heavy rider, off-road... 5hp? Not sure that's going to cut it...
But I've read mostly good things about the Hillard clutches on here. Personally don't think any centrifugal clutch will work in your application unless you gear it extremely low, like top speed 25-30kph. Otherwise the clutch will slip a lot, get hot and wear out.

WOW im surprised you didnt suggest a motorcycle engine.
Like Model said, a centrifugal really wont cut it for an off-road heavy kart. Even a torque converter wouldnt be that great with a 5hp briggs. You could probably get away with it if your geared it very low (8:1+).
Ultimately i would suggest finding a motorcycle, or atv engine, which will have plenty of power, a built in gearbox and a clutch of some sorts (plate type or CVT). This would take some custom fabrication, but its very worth it.

A 10 tooth clutch driver with a rear sprocket diameter nearly as tall as your rear tires would be one option but a jackshaft setup to allow an even higher gear ratio would probably be something you should seriously consider for better acceleration and off road/climbing ability. (but lower top speeds)
I think the Hillard Extreme clutches are probably one of the best choices in their price range. If your willing to spend more, theres better clutchs avalible.
