[AT] Backpack leaf blower

Fri Dec 3 08:41:22 PST 2021

When cold, the cylinder is smaller in diameter, so you get enough
compression to start with a worn ring. As it warms up you start to lose
compression as the cylinder expands to the point where the worn ring no
longer provides enough sealing and it stalls. Now, you may say that the
worn ring is also expanding against the cylinder wall, and it does, but not
as much as it should. It’s also expanding on its internal surface, so it’s
creating a gap at the piston groove, allowing the piston to essentially
flop around. That’s what allows the piston to hit the cylinder wall once
it’s not being kept centered in the cylinder. You can pull on the cord and
feel what you think is compression, but it’s mostly resistance from all the
other moving pieces.
