  Mark AlvarezJul 26, 2025
  If your Troy-Bilt Blower engine won't start, it might be due to several reasons. Make sure the EZ-Start lever is in the starting position and the throttle lever is set to FAST. Check if the fuel tank is empty and fill it with properly mixed fuel if needed. Ensure you've pressed the primer bulb fully and slowly 10 times. If the engine is flooded, pull the starter rope up to 10-15 times. Old or improperly mixed fuel can also be a culprit, so drain the tank and add fresh fuel. A fouled spark plug or a plugged spark arrestor could also prevent starting; in this case, replace or clean them. Lastly, consider the outside temperature; if it's below 40ºF or above 90ºF, it might affect the engine's ability to start.

  If your Troy-Bilt Blower engine lacks power or stalls, it could be due to old or improperly mixed fuel; in this case, drain the gas tank and add a fresh fuel mixture. Another potential cause is a plugged air filter, so replace or clean it. Also, a fouled spark plug or plugged spark arrestor can lead to these issues, so replace or clean the spark plug and clean or replace the spark arrestor. If these steps don't resolve the problem, the carburetor may need adjustment by an authorized service dealer.

  If your Troy-Bilt Blower engine will not accelerate, the issue might stem from old or improperly mixed fuel; drain the gas tank and add fresh fuel mixture. A dirty air filter or a plugged spark arrestor can also be responsible, so clean or replace the air filter and clean or replace the spark arrestor. If these steps don't solve the problem, take your unit to an authorized service dealer for carburetor adjustment.

  If your Troy-Bilt Blower engine won't idle, it might be because the air filter is plugged; replace or clean it. Another reason could be old or improperly mixed fuel, so drain the gas tank and add a fresh fuel mixture. If neither of these solutions works, the carburetor may need adjustment; refer to the Carburetor Adjustments section for instructions.

  If your Troy-Bilt Blower unit won't blow or vacuum, it could be due to a few reasons. The bag might be full, so empty it as described in Empty the Vacuum Bag. Alternatively, the tube or impeller could be blocked; clear the blockage as described in Clearing a Blocked Tube/ Impeller. If the impeller is damaged, take the unit to an authorized service dealer.
