Updated by Juan Velez

This bulletin covers the following Champion Power Equipment models: All Champion Power Equipment products instilled with a 717cc or 754cc engine.

Please read the instructions completely and carefully before performing the service.

  • To reduce the risk of injury, user must read and understand the operator’s manual before using this product.
  • DO NOT make any adjustments to the product without first stopping the engine and disconnecting the spark plug wire.
  • Burns from hot parts — let the engine cool completely before touching hot parts.
  • Injury from moving parts
  • To reduce the possibility of fire or explosion, be careful when working around gasoline. Keep cigarettes, sparks and flames away from all fuel‐related parts.
  1. The engine governor may need to be reset to WOT (wide-open-throttle) for the following reasons:
    1. After many hours (300-500 hr.) of operation to compensate for wear.
    2. If the carburetor has been removed for cleaning and re-positioned.
    3. If the generator is experiencing wide speed droop from HSNL to 100% load.
    4. If the generator is experiencing speed instability/speed hunting. 
  2. To reset the internal governor flyweights to carburetor throttle WOT position, do the following:
    1. Remove the main governor spring. If the spring is left on the spring, force can flex the governor link and cause a setting error, poor droop, and stability performance. 
    2. Loosen the M6 nut that tightens governor lever to governor shaft paddle.
    3. Use a light 2-finger torque [2-7 in.-lb. (.23-.79 N-m)] on the screwdriver to turn the governor shaft paddle screw CCW to seat the governor flyweights down at the WOT closed position. 
    4. Use a light 2-finger push on the governor lever towards the carburetor to seat the carburetor throttle lever up against the WOT stop.
    5. Tighten the M6 nut to [8 ft.-lb. (11N-m)]. Be careful not to push the governor lever off of the carburetor WOT stop. 
    6. Reinstall the main governor spring into hole #5.
