  Jennifer SandersAug 2, 2025
  There are several reasons why your McCulloch Blower engine might not start. It could be due to a flooded engine (refer to the “Starting Instructions”), an empty fuel tank (fill it with the correct fuel mixture), a faulty spark plug (install a new one), fuel not reaching the carburetor (check for a dirty fuel filter and replace it, or inspect the fuel line for kinks or splits and repair or replace it). In case of low compression, it is better to contact an authorized service dealer.

  If your McCulloch blower engine won't accelerate, lacks power, or dies under a load, consider these potential causes: a dirty air filter (clean or replace it), fuel not reaching the carburetor (check and replace the fuel filter if dirty, and check fuel lines for kinks or splits), a fouled spark plug (clean, replace, and re-gap it), or a clogged spark arresting screen (replace it). For carburetor adjustments, carbon build-up, or low compression, contact an authorized service dealer.

  Taylor DelgadoAug 13, 2025
  Excessive smoke from your McCulloch Blower engine can be attributed to several factors. The choke might be partially on (adjust the choke), the fuel mixture could be incorrect (empty the tank and refill with the correct mixture), or the air filter might be dirty (clean or replace it). If these steps don't resolve the issue, the carburetor may require adjustment, and you should contact an authorized service dealer.
