Carter UT High Speed System

UT high speed

Fuel is fed to the carburetor through the main metering jet C.

As the throttle valve is opened (higher speed), the velocity of air going through the bore creates a suction at the main discharge. This causes fuel to enter through the main jet C and mixes with air through jet K. The fuel air mixture travels through nozzle L and into the carburetor bore.

Adjusting M clockwise will leans the mixture. Counter clockwise will richen the mixture.
About 3 turns of the metering screw should get optimal speed.
