Actually walt...I am possibly improperly assuming it doesn't make business sense...
I don't know if one was more popular back in their day... you don't have production numbers do you? 254 vs 262
The 262 had to be more popular and shared parts with the 257. The 254 was a bit unique, an evolution of the 154. I guess they sold a lot of them but who's using them now? Nut cases like me...a small minority so no real market for them. Has to be more 262's still in use therefor more reasons to invest in tooling for replacement parts for the 262's. They had a different tank, although you can adapt I guess as the cases are about the same. The 262's have all different top plastic and intake related plastic due the different cylinder height. Just a lot of little things.....so unless they had a mind to sell whole saws, the 254 doesn't make any sense at all.
Bob had told me those were little hot rods...(254's) and he has a 154 that is an eye opener. But I didn't really expect much from them & didn't really internalize what Bob had been saying. A fellow at work has a family member working for one of those power line maintenance companies and had a pile of 254's, and then a shop sent me a couple more; like 8 or 9 between them total spanning their life as a product...early ones with the brass worm gear & aluminum seal holder, to later versions. Wanted me to see if I could scramble the pile into a couple of saws. I built 5 from that pile....then took the left over junk and built one for me. (yep..there is a couple of video's, think saw number one and 6 have video time) But learned that series because in that pile was every freaken wrinkle of that series! So they got spread around. Then a fellow working with the guys with the first pile blew up a 550...wanted to know if I could build him one of those 254's the same way I did the others.. (popup's & muffler mods & minor tweaks) so that started a ...trend. Won't go into the nitty gritty. But I have two now & another pile. One is on the tractor..
And I can go out, shake the snow off it and it will start on pull number 3.
SO working on this 036, it struck me there are a lot of similarities. BOTH closed port, simple, relatively light weight.....the 254 is smaller. And with a bit of compression they are snappy....smaller and lighter than the 262's AND the 036. Problem for me was the same group had a 262 and I repaired a 261. Really the big difference between the 261 & 262 seems to be the piston. But they wanted them bone stock, a restoration mentality because they were "cool" saws. The 254's go to work with them. The 262 stays on the shelf. Bottom line. And when I tested my "tweaked" 254's they were as strong as the 262's but are smaller and lighter....that it. Now I'm a fan. And will spend today debugging yet another 550 BTW....see my point? Liking those 242's and 254's more and more...
SO...given the question what old/obsolete saws would I like? No brainer. 254 first choice. 242 second. Thats it...
