Questions and answers
My Sherpa ST40-S keeps revving up and down, I have cleaned the sparkplug and air filter.
The Sherpa STS40-S revving up and down after cleaning the spark plug and air filter could be due to the following potential issues:
1. Carburetor Flooded with Fuel: If the carburetor is flooded with fuel, it can cause inconsistent engine performance. To resolve this, remove the air cleaner element, pull the starter rope continuously until the carburetor clears itself, and then reinstall the air cleaner element.
2. Faulty Ignition Module: If the ignition module is faulty, it could lead to erratic engine behavior. In this case, you should contact a service agent for assistance.
3. Incorrect Spark Plug Gap or Defective Spark Plug: If the spark plug gap is incorrect or the spark plug is defective, it can cause unstable engine operation. Ensure the correct gap is set between the electrodes or replace the spark plug with a new, correctly gapped one, as specified in the ENGINE OWNER'S MANUAL.
If the issue persists after addressing these points, further investigation may be required.
