Bob, you got a line on S25 rim and drum setups for 3/8's lp ?
I'm not aware of any, at least not in current production. I know they had them years ago for 1/4 pitch...
I have one in 1/4" pitch.........and recently obtained a 3/8-LP rim for it. Thank you gentlemen.......you know who you are. The rims are 9-spline and aren't easy to find in any pitch other than 1/4". There are a few out there still however. The 1/4" pitch XXV series Poulan application rim/drum systems (and separate 1/4"-9 nine spline rims) are still pretty easy to find.
There's a 'mystery' 3/8-LP 9-spline rim/drum system (for an unknown saw application) that keeps getting relisted on feebay. Somebody with an old Oregon catalog could probably tell us what saw it's for by the numbers. It's for a larger saw than a XXV series Poulan, as the drum is over 3" in diameter according to the seller's description.
On the Acres site, there's a listing for a 2400 Poulan that's very interesting. Now a 2400 actually is a rear handle version of a 2300AV Micro, but the Acres listing is for a Canadian market S25-CVA with a Windsor 'Mini-Pro' replaceable sprocket tip .325" pitch bar and a chain brake. The label on the clutch cover of the pictured saw (in the listing) clearly shows "Super XXV-CVA Mini Pro". I'd LOVE to see one of those saws 'in person'.
My guess is that it had the rim/drum system and a .325" pitch rim. I'm also guessing that there were 9-spline .325" pitch rims made for that 'mystery application' rim/drum system that I've seen on feebay. By the size of the clutch, it was probably at least a 50cc saw. Just for the heck of it, I'd like to try .325 pitch chain on an S25 saw someday. It must've worked OK, or they wouldn't have sold the Canuck saw with it...
I just got a good used 3/8-LP Windsor Mini-Pro bar that I'm going to run on one of my S25-CVA saws with my 3/8-LP rim/drum system. May even put a chainbrake on it (if I can get over the cost of it). I've also recently seen .325" pitch replacement sprocket noses for those Mini-Pro bars. I'm going to grab one if possible and put it aside. If I can scare up an NOS clutch cover decal for that Canadian saw (say from some old Canadian Poulan dealer.................Hey Tim can you help me out here???) then I'll have a good 'fake'.
Here are some Oregon #'s.
19779 is the number for the XXV series 1/4" pitch rim/drum system. I need to go get the # off of the drum itself. It's in the shop. I'll edit my post here with it later today.
18250 is the number for the 1/4-9 9-spline rim.
22580 is the number for the 3/8-LP 9-spline rim.
23115X is the number for the 'mystery application' 3/8-LP 9-spline rim/drum system.
