I purchased a Italkart shifter chassis today that has been converted to clone with the basic Blue HF motor just out of the box that still has the stock gas tank.
The kart shop I got it from gave me the mikuni pump, fuel line, and pulse fitting. They typ plumb theirs into the intake passage in the head casting, but said the pump often provides too much fuel so they also included a #65 keihin main jet I am supposed to install in the end of the fuel line where it clamps to the carb which supposedly solves the over fueling problem.
Do I need this jet if I decide to plumb to the valve cover instead?
I'm thinking the interruption of airflow in the intake due to the hole would make this a bad idea and that the top of the valve cover would be a better location.
