Was looking over my s25 saw parts bin.  I have 2 newer clutch drums with 3/8LP spur 6T

These 3 came with the 3/8 7T and 2x 1/4 9T. Guessing they are the 9 spline.  Can the 3/8LP spline still be bought? update:  Found them if wanted.
If not I may put the spurs on the other two.

From what I can see on my phone, that red saw doesn't have a dummy button.  The dummy on the auto only saws are different, and I don't think any of the red sears branded S25PS/VL saws were auto only. 

The manual oiler pushrod is either bent, out of engagement with the plunger of the manual pump (in the oil pump body), or both.  The oil pump will be behind the flywheel.  Auto only saws have no steel pushrod, and the pump will not have the manual oiler plunger section.

The plastic sliding kill switch will signify an older saw.  Same with the cast rather than stamped steel mufflers.  They also are likely to be 2.1ci/34cc rather than 2.3/38.   Sears used the teal and yellow colors before the red. 

The Micro series is a newer design than the XXV series, but both were produced at the same time for many years.  They're intended for different markets, although there was much blurring of the lines.  Tbe XXV series are my favorite tophandle designs, followed by the Micros.  The rest.....meh.  i do have a Husky 335XPT California to rebuild someday, but it's low priority.

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

Red and Blue ones have 2.3 right on the recoil.

Will you check your red ones and see if they say OIL right under the button? The blue and yellow have OIL, the red one dont.

I got 3 new air filters, just know time right now to get back at them.

Ah I looked but couldn't see the 2.1/2.3 on the saws.  Nust on the red.  Phone screen...

Don't think I have ever seen a sliding switch 2.3 before.  Just 2.1's.

I will check my red 2.3's when I get home.  At work on lunch break outside the building now.

That button looks more like it is sunken (and 'cocked') because something isn't right with the pushrod.  I could be wrong though.  Again....tiny phone screen....

That teal saw is a new one on me.  Have never seen a sliding switch 2.3.  I didn't say (or at least wasn't trying to say) that the red saw was a 2.1.  Looking back at my earlier post, it does show some poor choices of wording.  Trying to rapidly peck out a post and send it between signal drops...

The yellow saw most likely is a 2.1 though.  Is the exhaust port on the yellow saw bridged?  IIRC, the 2.1 cyls are not bridged, while the 2.3's are.  Do you have the 358.xxxxx # from the yellow saw?  That will get us the Sears IPL for it.  Piston, cyl, and ring part #'s from that IPL will tell the tale.  Think I only have one 2.1.  It's a Craftsman red 2.1A branded 25DA with the same straight handle as your teal saw.

If ya remove the FW cover/starter you should be able to see enough of the oil pump to tell if it is manual only without having to remove the FW.  The FW comes off easy on these too.

You're welcome my friend.  Lunch break over.  Hopefully I don't get drafted for a second shift tonight.  Supposed to go to the park for a GTG-prep work day Sunday morning...
