Husqvarna 288xp RING'S???

[briguy26]

Picked up this 288xp the other day, started on 2-3 pulls idles great throttles to full power no problem. I took top cover off and noticed an aftermarket cylinder on their so I wanted to check it out before selling. I pulled the muffler and it looks like previous owner put in (2) thin rings instead of one thick ring like it's supposed to have. Is this something any of you experts have seen?? Any info would be much appreciated.

Hard to tell if thats two rings or just one ring with a groove in it, which i have seen. Cant that working very long if it is two rings. Nothing to locate the ring not in contact woth the locating pin it would seem...

Seriously I thought I had seen it all!! Looks like a rebuild is in the near future.

I would poke at it with a pick, see if you can see them move seperately to be sure.

It looked like two I put a narrow head screw driver in there and pushed down on the ring and only one moved.

I poked at it again looks to move the whole ring, looks like a grooved ring. Now my question is... Why do they have grooved rings? This is the first I've come across I've bought and sold (3) 288xp's all of them had one thick ring.

NWP has supplied rings that look like that in the past. I wouldn't worry till compression is low.

Thanks for the info, everything else on the saw checked out fine. I think I'll see if there's any interest on A/S before I put it online.
