Keihin PWM 38mm Pump-Around Carburetor...
We start with an Keihin PWM 38mm carburetor and convert it into a "pump-around," for reliability and repeatable performance. To achieve this, the floats and needle seat are removed and a tube and restricter are inserted. |
|
Two fuel pumps (not shown) are utilized... One pump is used exclusively to pump fuel from the gas tank to the carburetor, while a 2nd pump is used to remove excessive fuel and return it to the tank. This system ensures that the float bowl has the correct amount of fuel, at all times. |
