DRUGSTORE LOGGER
Every one of the used saws I've purchased recently has had the wrong spark plug (according to the ipl, manual and acres site). I've cross referenced them and some aren't even close and some not even listed!
Has this hurt these saws?
I've searched and found the following thread which answers some questions but it isn't stated if there is damage to a saw if used with the incorrect plug.

Here is some of the knowledge gleaned from this thread:
"I know guys have used all kinds of other plugs with success as have I, but for the average guy this is the plug (one recommended by shop or sales person checking cross reference). The reason is The "6" in the Bosch number represents the heat range of the plug. And regardless of what "Billie-Bob" at the local parts store tells you, 6 in Bosch is different than a 6 in Champion, or ngk, or Denso, etc. Most foreign plugs the lower the number the hotter the plug. Domestic brands are the opposite.
So I ended up two heat ranges too cold........I wonder why I kept fowling plugs????????? I think this is an easy thing to over-look because spark plugs seem so simple. They can cause a lot of problems." spencer13ca
"In addition to the heat range and physical size, the non-screw top is specified (and needed)." Lakeside53
"I always try and run the same plug that came from the factory, my Polaris snowmobile came new with champion plugs, if I run ngk I will have fouling trouble, even though the cross reference chart says its the correct plug.
I'm thinking sometimes when you cross reference to a different brand, the heat range may not be exactly the same. I don't know how else to explain why else this would happen (assuming the catalog is correct)" yodayoda
I have had problems finding the Bosch plugs so have purchased a couple of the Autolite cross referenced ones to try (I didn't realize until today how many have the incorrect plugs and want to search out and purchase the correct ones from now on).
But back to my original question...Have these saws been damaged by using the wrong plugs and if so what kind of damage (a couple were way off in heat range!
Maybe the answer to this question will help some other members.
