Hi Steve, the last rings I played with was from a Farmall H I
rebuilt in the 90's. The only 2 cycle oil I use is the Stihl silver
bottle. The only reason I tried to remove them, is that they
wouldn't rotate smoothly using an awl. I thought that maybe there
was crud in the groove. <br>
<br>

<div>Hi Mike:<br>

</div>
<div>Sounds like a reasonable conclusion. Between getting work
done with a new one, and farting around experimentally with
the old one, you made the call that's right for you.</div>
<div><br>
</div>
<div>Have you played around with piston rings much in the past?
They are quite brittle to begin with. I'm not sure whether
overheating would make them even more brittle, but, maybe. I
think if they were seriously affected by heat, they might be
discolored too.<br>
</div>
<div><br>
</div>
<div>Another good call with concern about other internals.
Specifically, bearings. Mains, conrod, and piston pin are all
lubricated by that tiny bit of oil that's carried in with the
gas mix.</div>
<div><br>
</div>
<div>Hey, while we're here, I'll put in a plug for synthetic
2-stroke oil. I am a Stihl guy (Stihl vs Husky is like JD vs
Farmall or Ford vs Chevy!) and Stihl packages 2 different
products. Little orange bottles are the regular, "perfectly
OK" stuff, and for more money you get silver bottles with the
synthetic oil. I use silver bottles. What I have noticed
over time is that (a) the gas doesn't go stale (b) very little
smoke or smell (c) I have never, and I am not exaggerating,
NEVER purchased a spark plug. I've got a saw that's probably
about 15 years old now, a weed whacker must be going on 20,
and a hedge trimmer that I got at auction, who knows how old.<br>

<div> I did tear it down further and removed the piston, When
i tried to remove the upper piston ring it snapped and was
very brittle, I assume from over heating. I bought a new
blower, the exact same model, and will keep the old one as a
parts machine. One concern I had with just replacing the jug
and piston, is I don't know what internals might be damaged.<br>

<div> Hi Steve,<br>
Here's a better picture of the scoring, this
piston is literally the diameter of a silver
dollar. my reason for the first pic was to figure
out how to get the piston pin out. I may have to
send this in separate posts. <br>
<br>
Thanks,<br>

Here's a shot of the piston and the retaining
pin, not really sure how to get the pin out
since the retaining clip appears to be a washer
not a cir clip. I can order a new cylinder,
piston, pin, washers and and gaskets for about
$40, a lot cheaper than a new blower. Thanks for
any advice anyone can offer.<br>

my lovely wife was out blowing
leaves the other day with my
backpack<br>
blower, and it ran out of fuel.
She mistakenly filled it with
straight<br>
lawnmower gas, and after 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>
