Cool, thanks for sharing. It's always fun to hear about the good ol'days especially when it involves one of these iconic saws.I can tell ya that back in the day, the thin ring 2100's didn't hold up on the loggin' shows...many expiring before the season ended. Most of us were using PowerPunch @40:1. I will concede that some knotheads were convinced to run at like 16:1 still in those days with regular oils. It's very possible that with the thin rings, if too thick an oil mix was used the pistons lands would gum up with coke/carbon and the rings would stick...letting blow-by and reduced compression happen.
We didn't keep data or records then....we just got pissed, drew out own conclusions and bought another saw.
I never saw a jungle muffler on a 2100, but I have a J'red 80 I've used all these yrs that has one. We always had our mufflers modified and blanked the govs on the 2100's when we ran big bars. When I got down to 42" and smaller, I didn't bother.
The thin rings revved crazy fast because of the reduced friction, but they weren't running circles around the standard ring saws and causing any of us to pause in admiration. If you wanted a hot-ass saw in those days, you got a Walkerized saw.

I'm in a similar position. I recently acquired a 2100 with spark and decent compression but otherwise pretty tough. Debating rebuilding it or holding on to it as a parts machine for another one down the road. Will be watching for the answers to your questions. Thanks for asking them!Have read many threads. Posting my Q’s here as seems like the most info kept all in one place.
10 years ago I bought a Grandberg mill off CList for $75. Pic showed a Husky saw, which I wanted because the bar would fit my Dolkita. Owner said saw was seized, shop said not worth fixing, so he threw it in for free. Turned out to be a 2100 CD. Almost perfect bore and piston, and not seized, just worn out rings from bad air filter conversion. Shop pulled the intake, never pulled muffler. Dumb shop was my benefit.
After reading all the variations of this series, I decided it dig it out and start a rebuild. Don’t need a big saw, won’t be milling now, and it is mainly for fun. I want things done right, but won’t be a restoration or a production hard working machine.
So, here is what I have, and my questions:
1. PARTS SOURCES? Baileys has a few parts, Scott/Chainsawr has a few. I don’t trust most ebay sellers. Anyone here recommended suppliers or have parts?
2. PRODUCTION DATE for 2100CD, sn 5312819 Electrolux era
3. RINGS. ‘Thin rings’ B tolerance piston and cylinder in great shape and tolerances. Light gouge on intake from ingesting sawdust, no damage on exhaust. Rings are .33 mm thick (high) and 1.6 mm radial. Everything I find is listed 1.5 mm, which I assume are the ‘thick rings’. Since the piston matches the cylinder tolerance, I’d like to use it over and not buy a new ‘one size fits all’ piston. Where can I get thin rings, small end bearing 17x13x17 and circlips (those should be easy).
4. CARB PARTS for Tilly HS136C, with governor, which matches the manuals. Where can I get a full kit with gaskets, needle and seat, welch plugs and screens, and maybe governor parts?
-Is there any adjustment of the governor, or should I block it off?
-I saw discussion of HS149 carb used on some models, or maybe it was retrofitted. I have access to a 149. What are the differences, and should I consider changing? Do they use the same kits and parts?
5. FUEL TANK VENT ASSEMBLY is broken up. Any parts out there? Or can I install a grommet and small line and use some other vent?
6. FUEL LINE, WITH MOLDED GROMMETS seems ok, but source for new one? I think Baileys had this. Fuel filter appears typical replacement..
7. MAIN BEARINGS are good, but carboned/sawdusted really badly, and numbers aren’t readable. Seem to be standard 6203 C3. Sound right?
8. SEAL, FW SIDE seems like industrial standard.17x28x5 seal plus dust lip. Correct? or source?
9. SEAL,PTO SIDE on both sides of the oil pump, and the large oring/felt ring/rubber seal? on clutch side. Shown in manual but mine didn’t have it.
10. OIL PICKUP AND FILTER shows in manual, but I appear to have hose only. Source for new?
Edit: Solved. Found a pickup strainer that fit.
11. OIL PUMP ADJUST Manual describes two setting pump but not how to change the adjustment. Also, two different pump volumes listed. Anyone know the difference in construction and can a small one be modified to the larger delivery?
12. OIL PUMP SEAL for the two tiny in & out ports between pump and case. Mine missing. Were they small orings, or a gasket, or ??
13. EXHAUST GASKET MATERIAL to use? Std muffler, not jungle.
14. CLUTCH in manual refers to 1 mm of friction material. Mine is metal only, three shoes, about 1 mm radial clearance and looks like that is correct.
15. OUTER COVER WEAR PLATE missing. Looking for that.
16. DOGS, both missing. Probably removed for milling.
17. TOP COVER AND AIR FILTER missing. Has carb adaptor for round foam filter for milling, so I will probably just run that for now.
18. CHAIN BRAKE Have non brake cover, for milling. Would like to install a brake someday, but realize those cost more than I might have in the whole saw.
19. MANUALS needed. I have online links to good quality manuals, but can’t download or print. (The manualslib ones are almost worthless quality.) If someone has good files, or how to download certain files, I would appreciate.
Thanks for all I have learned and for all your time.

To ad to Kevin's post, the o ring for around the pump: I used a Cat 6v9746 on my 2100 rebuild. Been going strong for a few months now. They require a small stretch to fit but have a good seal and are the best quality o ring available.
I'm in a similar position. I recently acquired a 2100 with spark and decent compression but otherwise pretty tough. Debating rebuilding it or holding on to it as a parts machine for another one down the road. Will be watching for the answers to your questions. Thanks for asking them!
Tell me about it. I did a decent restore on Dad's saw and wound up with about $700 into it. Then I lucked out and found a second 2100 on kijiji for $240, put a tank on it and a 36" bar and 404 chain on it and away we go.I have one in the same shape...been debating for yrs on whether to keep it a part's saw and cannibalize from it......or restore back to woods shape. I hate paying all these stupid prices for 2100 parts. It's driven me to want a 394, which is a very close relative, but you can still get most parts for it. Forced to run a 394 because I can't get parts for a 2100 reasonably.....how fuc*ed up is that?

I have a friend who's really into metallurgy as well as being a ticketed millwright and heavy duty. He says the tanks are weldable and lucky for him I have two that leak for him to try it on.
