Compression 550 xp

[Kommandokenny]

I picked up two Husky 550 ‘s at the dump .

Guy at the dump is not allowed to scoop them.

He said some cottager in a land rover left them, saying both were running last year, but neither will start now.

So I gassed the better looking one up, it’s a 2015 with the A 12 carb.

Not even a burp, nothing .

It has spark.

I put a bit of gas in through the spark plug hole ,,nothing .

I noticed it was easy to pull and had the same resistance with decompression valve in or out .

I put the coompression tester on it and got it up to 3psi.

The other 550 had 50 psi .

So I had success with my 61 and a Chinese jug and piston so I pulled off the cylinder expecting a hole in the piston or a smashed in, wore out, ring and cylinder wall .

Nope the piston ring cylinder and piston all looked great [to Myuntrained eye].

Before I order a Chinese piston and jug ,,,,,,Am I missing something.
Sorry for the long winded explanation

Oh yeah. That piston is done. New piston and ring.

Check the cylinder. It’s almost certainly got some damage but may be just aluminum transfer that can be removed.

Ok,, I was not sure,, as the one I pulled out of the 61 ,was way more pooched .
I had good luck with China on the 61 and I use the saws for my own firewood.
It's a bit of a hobby, more than a living, so minor use the chineese jug /piston for 60 bucks is gonna be sustainable
Thanks for your input!
