Yes, you could instal a 1/4" Marine Primer bulb between the tank & carb, but you probably won't need it if you'll be using an electric kart starter on your KT-100.
I noticed your kart is set up for the engine on the Left side, did you buy that kart somewhere in Europe or Australia by any chance?
The reason I was curious is that's common in Europe but most all single-engine racekarts in the USA have the engine on the Right side...
