All the ones I listed are Tillotson carbs, have not seen any other make on them but the 070 and 090 are not that plentiful around here. I have only began researching for some extra info recently for a couple of future project saws I will be doing.

Excellent thread, answered a couple of nagging questions I had. I thought the HL-244A carb was the smaller version, only found on the 070.
I've figured out a way of telling the size of cylinder on an 070/090 without taking anything apart. I'm posting a copy here of a post I left on another forum.
If you look at the cylinder right over the clutch cover, you can tell if the cylinder is 090 or 070. I tried for some pics, but it's very hard to get it to show what I'm trying to explain. The easiest I can make it is, if the top of the transfer port ends between the 5th & 6th fins counting up from the rear corner above the clutch cover, it's an 090 cylinder. If it ends between the 4th & 5th fins, it's an 070.
Sorry, I can`t seem to figure out how to get the pictures to show up in the post!

It's the "bumped out" portion of the cylinder that can be seen between the fins to the right of the numbers in the pics. It sticks out past the "barrel" of the casting that has the piston bore. Look at the pics again and you will see what I am talking about. You can see where it ends at fin 5 or fin 6 on the pics.

090r
I was just doing some internet research and came up with a reference to an 090R. Anybody heard of that one before?

Not me but I am only in the learning curve about them right now. Did not pay much attention to them over the years as they had no use around these parts but I have reworkrd most of the smaller displacement saws and these are all that is left bigger than the saws that I have reworked and I would like to learn more about them before I tear into them for the refit.
