In fact, I have an 036 and I run a 18" bar with .325 x .063 chain on it (along with a 9 pin rim). My 024 is an older, and slightly smaller version of the 026, and both of those saws use the same bar, chain, and bar nuts. The rims and drive bearings would be the same except that I converted the 036 over to run a standard spline rim so that I could go to the 9 pin. Otherwise they would have both run the same drive bearing and could run the same rim. I use the small saw for limbing mostly, and for a back up. I've found that an 18" bar is about the ideal size for bucking firewood, and when combined with the .325 chain and a 9 pin rim, it's pretty fast. Until I get into wood that's over 24" diameter, I don't see any gains in using my 064. Between the 036 and 024, the trade off seems to be about 4". I've run a few 026 saws, and I've always thought that they were noticeably faster than my 024, so the 026 will probably run just as fast as an 036 in wood that is 6"~8". So not only would you be getting a good saw for limbing, but you'd also have a saw that, in spite of its light weight, can do a good job of keeping up with your bigger saw when it needs to. Having the same B&C on both saws allows me to minimize the number of chains that I need to keep on hand and/or take with me. It also lets me get a lot more use out of my bars because I wear on different parts of the bar when limbing than I do when bucking. So when the bar on the 036 starts getting to the point where it needs changed, I swap it with the one on the 024 and keep on going.
