Default How do you "tune up" a hard-to-start Craftsman 18" chainsaw

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.


Husqvarna, and some other chain saws, have had problems with the
plastic gas line inside the gas tank cracking. When it does, the saw will
be hard to start or not start at all. In many of these saws it is easy to
replace the plastic tube with one of better quality, and replace the
filter at the same time. A saw shop can do it for you, if yours is bad,
or will sell you the improved fuel line.

You can check the ignition by pulling the start cord and observing the
spark plug gap. Naturally you have removed the plug and have it
touching the electrical ground of the chainsaw.
