Why is the engine speed unstable on my Powerhouse Portable Generator?
- MMichael BlackwellAug 10, 2025
If your Powerhouse Portable Generator engine speed is unstable (too high or too low), consider these potential causes: * **Carburetor:** A faulty carburetor may be the reason. Inspect, disassemble, and clean it. * **Economy Switch:** Inspect the economy switch. * **Throttle Control Motor:** A faulty throttle control motor (step motor) can cause unstable speed. Inspect the wiring and the motor itself. * **Inverter Unit:** Inspect or replace the inverter unit if it's faulty. * **Valve Clearance:** Misadjusted valve clearance can lead to speed instability. Readjust the valve clearance.
