engine cut off clylinder: was Education thread

[Ralph L. Fullenwider]

Larry:

If your talking about the single piston cylinder, engine cutoff, only two
screws hold it together. There are 2 O-rings in it. a small one that forms
the gland nut and one on the cylinder rod base. You can get o-rings for the
small one from ACE hardware. Then use a scribe pick point to remove the old
one, lube the new and insert it. The other o-ring is different, it is
skirted, so to speak to form a tighter seal on the cylinder walls and
allows less air to blow by. Most of those cylinders, it is the front small
seal that leaks.

Safe travels,
