CV17-740 engines in this series are equipped with either
a Nikki or Keihin one-barrel, fi xed main jet carburetor.
Some applications use a fuel shut-off solenoid installed
in place of fuel bowl retaining screw, and also an
accelerator pump. All carburetors feature a self-relieving
choke.
CV750 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.
Troubleshooting Checklist
When engine starts hard, runs roughly or stalls at low
idle speed, check following areas before adjusting or
disassembling carburetor.
1. Make sure fuel tank is fi lled with clean, fresh
gasoline.
2. Make sure fuel tank cap vent is not blocked and that
it is operating properly.
3. Make sure fuel is reaching carburetor. This includes
checking fuel shut-off valve, fuel tank fi lter screen,
in-line fuel fi lter, fuel lines and fuel pump for
restrictions or faulty components as necessary.
4. Make sure air cleaner base and carburetor are
securely fastened to engine using gaskets in good
condition.
