Why does my Poulan Pro PP19A42 Lawn Mower engine backfire when turning it off?
- KKelly BryantSep 14, 2025
If your Poulan Pro Lawn Mower engine backfires when turning it off, it's likely because the engine throttle control was not set between half and full speed (fast) position before stopping the engine. To prevent this, move the throttle control between half and full speed (fast) position before stopping the engine.
