Have a 5 year old 562 xp.
This year, had an issue with getting fuel to carb, determined it was a rotted line inside tank. Replaced the rotted line and put saw back together started to run lean after warming up.
Thought it was an issue with how I put it back together, reversed the process and then re-did it more carefully. Still ran lean after warming up.
Starts easy, cuts fine (no issues with power), but runs lean. It has not run much since but did spend a few minutes cutting wood in a lean condition - like I said, would start to go lean after warming up.
I did not want to spend any more time chasing dead ends and running a saw that was lean, so I took it to a repair shop to hopefully find the issue and prevent further damage.
When I spoke to the shop mechanic, was purchasing parts for another saw, and asked if he would have a chance to look at it, he told me that it was probably not worth fixing and should plan on buying another saw. I asked him to take a look anyway and dropped off the saw.
I got a call a couple weeks later, he finally had a chance to look at the saw. He said it had a torn boot, and was packed with dirt and debris which was causing the lean condition. He said that the piston or jug was ruined and I would be looking at $300 in parts and the same in labor so I should buy a new saw.
I don’t doubt any of the things he told me but do not want to throw in the towel on this saw.
I am capable at most mechanical tasks but would prefer to ensure that I am going about this correctly.
So, based on what I have been reading, I need to, obviously, replace the torn boot and determine what exactly is wrong with the piston and/or cylinder. So, I figured I would ask about the appropriate procedure on here to assess my damage. I have seen in many other posts, people sending pictures to the forum for advice and I plan to do that.
What would be the first thing to do: Should I check compression? Do a leakdown test? Open it up and look?
From there, what should step 2 be? (i.e. - if compression is good, do leakdown test, if compression is low, then look at piston).
Thanks in advance.
