Generator Run, but has a rough start / IdleUpdated a year ago

If you happen to be having issues with your generator experiencing a rough start or rough idle (Revs from high to low RPM), please follow the suggested tips down below.


  1. Test the Battery For Voltage. Please note, the battery should read 13.5 volts when NOT under load and 11.5 to 12 volts under load.
  2. Inspect the condition of the spark plug and replace to a NGK spark plug recommended for your specific generator.
  3. Check for Choke Position and Operation (Please note EH will have a manual choke)
  4. Inspect the Air Filter Assembly box to make sure it is sealed properly
  5. Inspect Fuel lines for any leaks in the system
  6. Inspect the Linkage for Damaged or Worn / Stretched out springs
  7. Inspect for Bad ignition coil or bad spark plug wire
  8. Try Low Oil Sensor Bypass (CLICK HERE) Low Oil Sensor Bypass Test
  9. If low oil sensor bypass does not work and spark is still the issue it may indicate that the ignition coil is faulty (After replacing the spark plug)
  10. Lastly, we would recommend resetting the valves (Valve Lash). (CLICK HERE) On instructions how to adjust valves

 

Potential Part Replacements Based off Symptoms:


Air Filter/Assembly: If air filter is dirty or damaged, recommend replacement

Fuel Selector: check for physical blockage/ or damaged

Ignition Coil: Replace this part if spark seems to be the issue and wire disconnect and plugs do NOT work.

Linkage Components (Springs & Brackets) : Physical damage, stretched, broken replace this part

Governor : If the unit climbs in RPM and linkage checks to be good, there could be a failure at the governor.
