Have you looked for an exploded view of the piston and associated parts? If you do it might give you an idea of how the pin is held in place. Possibly the washer is pressed fitted in to hold the pin in place. The new washer may not be flat, it might be cupped. When you drive it in you wind up flattening it and in turn it expands to hold the pin in. Can’t really tell from the photo, but maybe it has something to do with the indentation on the side of the piston. Do a search on replacing the piston for your blower and see if somebody posted a YouTube video of how to do it.<div><br></div><div>$40 for Husqvarna parts sounds like a good deal. A lot of manufacturers use common parts which I think helps to keep costs down across their product lines and everybody else’s.<br><div><br></div><div>Carl<br><br>On Wednesday, December 8, 2021, Mike M <<a href="mailto:meulenms@gmx.com">meulenms@gmx.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Hi Moe,<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>
<br>
Regards, Mike M<br>

<div> So I pulled apart my leaf blower today, and looked at
the exhaust port, as was suggested. Heavy scoring on the
piston. So you were right, she ran it with straight fuel.<br>

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>
