Air Pump Test

  1. Detach air pump outlet hose from by-pass valve. Insert "T" fitting and connect pressure gauge. Plug other opening in fitting.
  2. Be sure air pump belt tension is correct (deflection is about 3/4" when depressed midway on longest run). Start engine and run at 1500 RPM. Be sure choke is pushed fully in.
  3. Check pressure gauge. If reading is below 1.0 psi, replace air pump.
