I cut down a few trees this past weekend and was sawing them into logs when
the chainsaw stopped suddenly. I'd last used the saw in the fall and had n
o problems with it. When I tried to start it again, it wouldn't and there s
eemed to be less resistance to the pull than earlier. I was getting near th
e end of the day anyway, so I packed up and went home.
I checked the saw and found that the spark plug was a bit loose. I tightene
d it and it ran perfectly. I've never had this happen before with any small
engines. I wouldn't have thought that vibrations would loosen it, as it's
attached to the wire with a tight rubber boot. Has anyone ever had this hap
pen to them?
