Make sure it's not a Champion brand plug. they had a run of defects.
I've bought Autolite, or NGK. If it fails to start, look at the spark
plug. Wet? Flooded.

Champion RCJ7Y. None of the stores carried that but they told me a Champion
CJ7Y (without the R) is the same thing so that's what I put in there.

The plug, when pulled out hot, is dry as a bone so I'm pretty sure flooding
isn't the culprit. I'm beginning to suspect either the plugged fuel filter
(I didn't know chain saws HAD a fuel filter) or the spark coils are bad.

Don't know how to test the coils though.

If the plug is hot, it's prbably firing. You can check this by pulling the
plug, resting it against some metal and hold the saw steady while you yank
the cord (have someone help, just keep them away from the blade!)

If it sparks, start looking for fuel not getting there.

Um, when I was in telephone support, they told us the FIRST question to
ask was, Is it plugged in? I said, "you're kidding!" 30% of most problems
were because it wasn't...

So, full tank? Fresh gas? And, is the fuel shut off closed?
