Hi Steve, cylinder is hard plated and is scored on the exhaust side.
Looks like the engine is toast. It took me me forever to tear it
down. Looks like a new blower is in my future. It would cost me more
to have a machinist repair it than to replace it.<br>
<br>
Thanks,<br>

<div> Hi Brian and Carl, yes when it dies it will still pull
over easily but it will not start. At this point, I've fully
torn it down, and the piston is really messed up. Looks like
a time for a new one. I have about 2 acres to blow clean, so
no 5 minutes Brian LOL.<br>

<blockquote type="cite"> 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.

One more thing that you might be able to do is
push the piston down, pull the spark plug, and try
to see the wall by looking through the spark plug
hole.

my lovely wife was out
blowing leaves the other

a bit it started to
stumble and then quit.
She<br>
came in to tell me about
it and ask what the
problem was. When I
looked<br>
at the tank I noticed
there was no blue tint
in the gas, and I asked
her<br>
what can she filled it
from, and she pointed to
the gas container I use<br>
for my zero turn. I told
her that was straight
gas, and she needed to<br>
use the 2 cycle mix,
that is in another red 5
gallon can, honest<br>
mistake. She claims I
told her to use that
fuel, when I know I did
not. <br>
I used it today and it
will run for about 5
minutes and then sputter
out<br>
and die, like it's
running out of gas. It
will restart, but then
the<br>
same scenario starts all
over again. Is their any
chance of saving this<br>
engine? Maybe a higher
oil/gas ratio? Thanks in
advance.<br>
