    we are running a crg cadet kart with kt in the jr sportsman class. My question is when I got this kart I noticed that the fuel outlet from the tank was at the bottom of the tank. Someone had added this and was wondering what everyone’s thought was with that set up. I guess the theory is the pumper does not have to work as hard to get fuel, but one person said they thought that it would over fuel the motor.

    Won’t hurt a thing! I have top-bottom- side- and sump tanks on my various karts, all with different motors, all work fine.

    Thanks for your feedback. Another question I have is what is your opinion on running a fuel filter or not on at kt

    It’s a must to run a fuel filter on a KT100, the internal carb screen is very small and will clog quickly.

    As long as there is fuel in the line it could go over the empire state building because the fuel on the down side will balance the fuel on the up side.

    Get a filter made for two stroke fuel. Walbro makes a nice one. Try to mount it vertical so it doesn’t trap a big bubble.

    At my track I have always seen and myself included the filter horizontal about 6 inches out of the carb. Are you saying it might be better vertical, say alone side the fuel tank where the fuel line is routed?

    It doesn’t matter where it is or how it’s hanging as long as it doesn’t have a big air bubble in it. Mines hanging just below the carb so I can grab it and hold it so the air gets out.
