Cold Start Valve
- Engine temperature must be less than 85°F (30°C). Disconnect cold start valve mounting screws and remove valve with harness connector and fuel line attached.
- Remove and jumper ignition coil secondary wire to ground. Attach metal housing of cold start valve to ground. Direct cold start valve injector into a clean container. See Fig 1
. Have assistant turn ignition switch to START position and observe cold start valve spray pattern.
- The valve should deliver a consistent cone-shaped pattern until thermo time switch interrupts fuel flow. Ensure valve does not leak after fuel flow stops. If spray pattern is uneven or inconsistent, check for plugged or defective cold start valve. If valve does not function, proceed to THERMO TIME SWITCH below.
