Does anybody know if a 12V battery powered weed whacker motor would be enough for a go-kart? Gasoline is just too expensive.

I think it would might work. The little electric go karts at walmart only have 200 watt motors so if the motor you're looking at has more than say 250 - 300 watts you should be fine.

Also check out these two motors. 3.5 hp may not sound like much but trust me it's more then enough power for a go kart. Keep in mind 1 hp is 745 watts

I might actually build a mini-tank, with 2 seperate motorized treads, 2 average electric motors should run something like that without the wait of a driver.

Bad idea. You would eventually kill it turning, because the treads on the inside of the turn would have a shorter turn radius than the treads on the outside of the turn. Tanks do it, but they tear up streets too. A mini tank won't tear up the streets, so the pressure would be taken out on the motors or on the connnection between the motor and the wheel.
If you don't believe me, take a 4x4 truck and drive it on the pavement.

You could have four wheels with "mock" tank treads.
