I heard from a Australian company that specialises in the KT100 that I should run 18:1 fuel/oil and the jetting should be:
KT100S Bitumen
Jet – Low 1 3/4 Jet – High 1/3
Flex Length 65mm flex length
Fuel/Oil Ratio 18:1
Hi everyone, recently I bought a KT100S go kart. It ran fine when I bought it however does not work when I bring it back home. I adjusted the high speed and low speed adjustments and fiddled with the idle screw on the carb, but it turns out that the carb was perfectly tuned before messing it up...
