The 026 P&C will bolt on 024. There are 2 cranks in 024. One has non caged rod brg. (old AV model I think). Late model has caged rod brg. (AV Wood Boss) it's good to go for 026. One prob. converting is 024 cylinder cover won't work. 024 cyl is shorter ( has flat top) 026 cyl. has vertical cooling fins on top of cyl. (taller). I converted one a couple of years ago. I changed the 024 cyl cover, AF cover and AF to 026. 026 has a bigger AF. There are two different 026 AF style depends on fuel tank vent. You'll probably need the old style 026 AF.
Al just do a little "Al magic" to the 024 and she would be OK as an 024. I wouldn't do it again unless I had a bunch of 026 parts. I wound up with way too many dollars in it. After buying all the stuff I needed to convert. I'd do a WP one the 024 cyl. and call it good.

Al, I did a reply on the other site (Competition Saws) with what I knew about 024's. Too much to retype.
