Great replacement for Poulan Pro Chainsaw OEM
The OEM sparkplug for my Poulan Pro chainsaw isn't made anymore. At the beginning of spring the chainsaw didn't want to start and when I could get it started it would die. I replaced the spark plug with this one because they no longer manufacture the original plug. It looked a little long but it fit ok. After I installed this plug and a new air filter, chainsaw started right up and ran without dying.

Works well
It cracked while I was trying to replace it with the old one because I tightened it too hard and had to buy another one from the store

Brought my Poulan PP4218A back to life.
Have a Poulan PP4218A chainsaw that was very difficult to start after just a few short excursions. Left it in the case for a couple years, then tried tinkering with it again. Before the spark plug replacement, the saw would start then die after one second. Now it starts and stays operational after 5-6 pulls at a cold start. Couldn't be happier, since I was about to throw this chainsaw away.
