So I have been digging around the forums and cant find this particular information, so why not start a thread? I just got my blue c series running, but when it came to me all of the markings, decals, and badging are gone. In my research I have tried to find out what the differences are between the generations and displacements of these saws. Here are some of the differences I have found. Feel free to correct me on this.
C5/C7/C9 all have single stack mufflers, later models have the three point mounted mufflers c5/7/9 all came with fairbanks morse starters. Later generations varied from what I can tell. c5/1/2 all came in metallic blue whereas 7 and 9 series came in red and green c9 series had pyramid reeds while 5 and 7 had single reed valves all C series came with the same phelon/wico points ignition system
I cannot find any other external differences or similarities, and besides paint the only real way to tell the difference is measuring the jug.

Thanks for starting a thread on this. I have been wondering about these c-series more as i ended up with two of them, a c-52 and c-72. The only reason they were built i guess is for running other attachments like a drill or auger. I am not to fond of them yet, but we will see. I hope others here will discuss their advantages if any.

Id love to know more about them. Theyre great saws but reading is hard to find on these beasts

Although rare, the C51-71-91 series also had optional auto oilers and optional gear drives.

The Homelite literature collection there is by far the largest on the Internet.

The C-91 has an idle adjustment screw accessible from the outside of the air filter box, the screw presses against the throttle linkage. I *believe* this was the only saw in the series to have this configuration, makes it easy to spot. I also believe all the C-91s had the overrunning bearing starter. I also happen to have one

Here's a C-91 that I traded for recently. I used to carry one as my backup when I was cutting up tornado blow-downs as they had all kinds of twists and tension loads on them causing them to pinch a saw easily. It ran 7/16" chain which helped make a little wider relief kerf to help relieve the tension in the log/trunk. youtu.be/yzYvxwhDy5g

I noticed the handle is different tham my c5. I wonder if the difference is generational or size?

But, I grew up om manual only saws, so I don't look to see if they are auto too. My right thumb is twice as big as my left. I need to find a C9/91, I just love the red and green.

Another difference i have noticed between the first generation and others is the air filter cover. The firdt gen has a sleek design while later models have the gaps down the sides

One other thing that I find interesting is that the C-52 went back to a fairbanks morse style starter when the previous C-51/71/91s had the bearing overrun starter.

I have always been curious about that too. I think a lot of times it just had to do with the parts they had available. My 707g for instance has a FM starter when most saws of that era have the overrunning starter. I've worked on both and they both have their quirks for sure.

I had an overrunning bearing starter on a XP1020 that locked up on the inner race and virtually locked up the whole saw. I ended up taking a 1/2' impact and hit the clutch nut in forward and reverse until it finally let go.
