Spark plugs - one more time

329 Views 3 Replies 2 Participants Last post by  **DONOTDELETE**
I replaced my spark plugs recently. The 225 had Autolite 65 plugs, but I got Champion RJ12YC plugs from Checker. When I compared the two, the 65s were about 1/2" longer on the electrode end. The Champions seem to work fine, but I was wondering what difference the shorter length will make. I have seen both listed in various posts here as acceptable for the 225.

Errrr...... The numbers look correct, have you looked on the plugs themselves to make shure the plugs are really what the box says? I have seen plugs in the wrong box before. I don't have any champions here to compare at the moment. Who knows, it might be fine.

It's a 225? Who made the 225?

Why try to make something else work?

Why not stick with the same plug the engine was designed for? AC's!

The plugs agree with the box. Like I said, it runs fine...
