Just checked the yeller saw IPL.  Lists 530011244 for the cylinder.  That's the 1.438" cylinder for the 2.1ci saws.  Also lists 530023389 as the piston.  That's the 1.435" slug for the 2.1ci saws.   

Of course, the p/c could have been swapped some time in the last 30+ years or so.  Don't really matter.  I haven't been able to detect a difference in power between the 2.1 and the 2.3.  Maybe with identical chains on the same day in bigger wood with a timer buddy who's very consistent with a stopwatch.....

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.

My red S25-CVA's.  Black/white decal saw is a 2.3PS/VL like yours.  Black/Green label saw with the black AF cover is a "Craftsman Pro 2.3VL" or something similar.  Can't recall right now.  They're next to my 5.2/30 branded 5200.

Think I am going to put a 3/8LP on the 2 roller nose bars that had 1/4.  Have 2 3.8lp spur 6 and the red one is rim 3/8lp 7

Any idea the drive link count on these rollernose bars?

You've got it Kevin.  They have a duckbill held in the tube section on the underside of the cap with the star washer.  Washer slips over the duckbill and then is pressed in as far as possible.  Sometimes, the plastic gets chewed up by the 'points' of the star washer and allows the washer to slip a bit.  Gas then leaks around the flange of the duckbill and pees out the hole in the cap. 

When replacing the duckbill, it helps to clean ALL the old duckbill goo out of the cap.  Also helps to flatten the star washer out after removing it.......as it tends to get deformed.

If they're 16" then they should be 56DL.  Could be 57DL too.  Seen both on these saws.  The Windsor Mini-Pro 16" bar on my 2.3PS/VL took 57DL of LP.  It's the rim drive like yours (9 spline), so it should be 7 pin.

Not sure on the bar length. I counted the 3/8lp on hardnose and 1/4 on the 2 rollernose when I took them off but I cant remember.  :-[

Really need to get them back together and clear bench 3 off.

Refresh my memory on the 2.3 bore please.   I just measured the yellow one that we are thinking 2.1 by IPL but it has the bridged cylinder like a 2.3.
Through the exhaust port and I use soft solder to mark.  37mm is what I came up with as close as I can get it.   Using converstion chart 1.45669"   so just guessing this will come back to bridged 2.1ci then?

Just noticed the red one the bar wasnt a hard tipped bar. It was a sprocket nose with 57DL 3/8LP chain with 501 on the drive links.

The 2.3ci saws have bore that's a hair over 38mm.  Around 1.5".  Don't have the exact number in front of me right now.
