Why Poulan Pro Snow Blower does not start?
- O
  oreyesAug 14, 2025
  Your Poulan Pro Snow Blower might not start due to several reasons: the safety ignition key may not be inserted (insert it); the fuel tank may be empty (refill with fresh gasoline); the ON/OFF switch may be OFF (move it to the ON position); the choke might be in the OFF position (move it to FULL); the engine might be flooded (wait a few minutes before restarting, without priming); the spark plug wire may be disconnected (connect it); the spark plug may be bad (replace it); the fuel may be stale or contain water (empty the fuel tank and carburetor, then refill with fresh gasoline); or the fuel line may be vapor locked (ensure the fuel line runs continuously down from the fuel tank to the carburetor).

  If your Poulan Pro Snow Blower experiences loss of snow discharge or slowing of snow discharge, consider these potential issues: the belt may be worn (adjust the drive cable); the auger v-belt might be off the pulley (check and reinstall it) or worn (check and replace it); the discharge chute could be clogged (clean it); or the augers/impeller could be jammed (remove any debris).

Why Poulan Pro Snow Blower lights are not on?
- E
  Elizabeth MayAug 26, 2025
  If the lights on your Poulan Pro Snow Blower are not on (if equipped), it could be due to the motor not running (start the engine); a loose wire connection (check the wire connections at the engine and both lights); or a burnt-out LED (replace the LED light module, as individual LEDs are not replaceable).

Why Poulan Pro Snow Blower engine idles roughly?
- B
  brenda95Aug 29, 2025
  If your Poulan Pro Snow Blower engine idles or runs roughly, it could be due to: the choke being in the FULL position (move it to OFF); a blockage in the fuel line (clean it); stale or water-contaminated fuel (empty the tank and carburetor, refill with fresh gasoline); or belt stretch (replace the auger v-belt).

Why Poulan Pro Snow Blower rotator is hard to move?
- P
  pamelamoralesSep 5, 2025
  If the rotator on your Poulan Pro Snow Blower is hard to move, there might be debris in the chute rotator mechanism (clean the internal parts) or the cables may be kinked or damaged (ensure cables are not kinked and replace damaged cables).

How to fix Poulan Pro Snow Blower recoil starter hard to pull?
- J
  James RichardsonSep 9, 2025
  If the recoil starter on your Poulan Pro Snow Blower is hard to pull, it may be due to a frozen recoil starter, see “IF RECOIL STARTER HAS FROZEN” in the Operation section of this manual or the rope is interfering with components (recoil rope should not be touching any wires or hoses).
