How do I replace the spark plug on my snow blower?

  1. Ensure that the blower has been turned off – remove the ignition key before you proceed.
  2. Gently remove the plastic cap attached to the front end of the spark plug housing near the plug boot. Be careful not to drop any loose debris into the spark plug housing.
  3. Deactivate the spark plug circuitry by disconnecting the spark plug boot
  4. With the help of a socket wrench or a suitable tool, carefully remove the old spark plug.
  5. Inspect the new spark plug before inserting. Check that the plug’s gap is as per the recommendations mentioned in the engine manual – if not, reset the spark gap. You will need to check the spark gap from time to time.
  6. Re-fasten the replacement spark plug into the plug’s housing and tighten it with the socket wrench.
  7. Activate the spark plug circuitry once more by re-connecting the plug wire and proceed to install the plastic shield over the housing.
