Troubleshooting a Surging Engine |
If your engine is surging or running unevenly, chances are that something is wrong. Some engines will seem to surge when there's no load because when the drive, auger (if a snow blower) or blade (if a mower) are disengaged, the governor will keep it from reaching full throttle. If the engine still surges while there's a load on it (or it dies out completely), here are some quick tips to troubleshooting an engine surge:
- Carefully inspect your fuel line as your fuel line may be clogged, dry-rotted or broken
- Drain your carburetor and fuel tank as you may have water in the fuel
- If the machine is equipped with a fuel pump, check to make sure it is working properly.
- Inspect your governor as it may be set improperly or sticking in place.
- Clean, rebuild or adjust your carburetor. Always start with an adjustment and then move on to larger projects such as cleaning or rebuilding the carburetor.
