If you want a proper karting experience, go to a real kart track at an event run by a karting school. I went to the track up near Sacramento and the school was run by a world champion in kart racing. The karts are gas powered, will be fast and they are properly set up.
I went with a group of friends, many of whom raced with the AFM. (Essentially we rented the track.) They even let us have a real race. We all went off in formation and when we came around to the start/finish, we got the green flag and we were off racing at full tilt. I was in the front row and got to experience going into the first turn with an angry pack of racers on my ass. The entire day was an amazing experience. One guy brought his own kart and forgetting to tighten a nut, went off track and flipped himself and his kart over a 6’ chain link fence. He and his kart were banged up but OK. At the end of the day he put on his rollerblades and a weed wacker motor with a propeller on attached to a backpack frame for a couple laps around the track. Great times!
