CH18-740 engines in this series are equipped with either
a Keihin or Nikki one-barrel fi xed main jet carburetor.
Most applications use a fuel shut-off solenoid and also
contain an accelerator pump. All carburetors feature a
self-relieving choke.
CH750 engines in this series are equipped with a Keihin
two-barrel side draft design with fi xed main jets. A self-
relieving choke similar to that used on single venturi
carburetors is also contained in design.
