I just received my (correct) 1 1/2" by 1/16" rings from Otto Engine Works for my s25da on Friday. I stayed up late and finished off my barn find with some new goodies. This one was quite different than the 3400-4000 series saws to say the least. The compression feels robust without the base gasket and the sound and throttle response are sublime. I have not touched it down in wood yet. I can tell I will be wearing some anti-vibe gloves for this one if I plan on cutting with it for an extended period of time. Kind of makes you feel...alive. I like it.
Thanks to Nate for the starter grip handle and handle insert.
Great job on the S25 series. Robust compression as in 140# or so? Glad the Otto rings worked well for you too.
Was someone looking for Poulan 361 / 306 rings? I can do a search, as I've posted the aftermarket replacements on here before. They're on Flea Bay (OEM Homolite) or you can get them from the Greek if you would like Cabers. These are the correct 1/16" thick rings too!
The rings are Homelite Super XLAO rings #59436-1a, and I know I had to fit them to the bore though, 2 minutes per ring.
Thanks for setting me straight on those metric rings Randy. It was fun putting it together in the end once I had things sequenced properly. I ran a tank through it last night and it is impressive. Noodles galore when blocking up some rounds of Cherry. I did find setting the carb to be a bit tricky. It really likes it rich on the L to get the snap off the throttle > 1 1/2 or so. Can't speak from what is normal with these saws, but it received a full kit and metering arm set using "W" tool. It does seems to idle all day long and starts/throttles effortlessly. The auto oiler is weaker as I expected, and doesn't put out unless at moderate throttle. The manual is healthy. How did you manage with your experiment on the diaphragms for the pump? It would be nice to use some of that material to fix up these pumps.
"Robust" is my qualitative assessment of the compression- LOL. I am that guy that doesn't have all the tools in the collection yet. Namely a compression tester. I can tell you the saw thumps really hard when turning over slowly, will bite back if you don't pull smartly and will hang static with full tanks + b/c from the cord.

I think I fixed up one of those in weed eater colors for my neighbor. I thought it was sort of like a brick that didn't blow too hard.I got me a wild thing
Sweet, that's a good feeling when a plan comes together like that! Those saws with the Tilly HUs do seem to be finicky on carb settings, I usually have a small screwdriver in my pocket when limbing out with them. The idle mixture is what I'm chasing most of the time.Thanks for setting me straight on those metric rings Randy. It was fun putting it together in the end once I had things sequenced properly.

Just to clarify - you're sayin the sxlao rings will fit with some slight file action? That'd be great cause everything else I can find is way too big or too small Where did you find them?

I doubt you would see any gains on a guage between the two, but the gap is now closed to 0.008" cold.
Those Poulans had an issue with blow by, from seeing all the original pistons carbon browned on the sides from the combustion gases.
Of course they've been cutting wood for over 30 years now!
Sounds an issue with the impulse. Just my $.02Did some cutting today, older 5200 would not draw fuel from tank, just put new fuel line on it last week, ran great before that . 4000 ran great as usual. 8500 ran great also
