Used Go Kart for son

[ohiophoto]

I just bought my son today a go cart has a briggs 5 hp (Bought it at a garage sale) and i put a new clutch on it. Took it to my brothers and it wont climb the slightest of grades. On flat ground it flies (More than he needs hes 7). I have been reading and seen the comet converter kits. It has golf cart tires on the rear so i figure it needs one of those. If anyone can give me advice on how to get more bottom end torque. Thanks. I will be ordering a comet converter tomorrow.

Thanks

Since your son is young, the top speed is probably not that important to you, right? If that's the case you can change the gearing on the jackshaft and/or put a larger sprocket on the axle. This will give you more power to climb grades but a lower top speed.

My son's 4-1/2 so I have the same concerns... slow and steady.

Thanks yes my son is a speed freak as well!
I will be gearing it down this winter! I would like to put a tachometer in it! Some may think i am nuts but he will think its cool! I was wondering if anyone had any ideas how to I figure I need a motorcycle tach.

Thanks
