Help with ID of old parts

[nmurph]

Ok, I have some parts I've had for several years. I came across them today while doing some clean up in the shop. They came to me a parts lot from someone who was cleaning out their late dad's saw shop. Here's what I have. Dust of the brain cells and help me figure out what I have-

First are some carb diaphragms--

Lastly- ID's???

 

[Big_Wood]

this is just a guess but for some reason i wanna say the clutch drum is for a stihl 08s. i haven't worked on any of those saws for a while but the clutch drum looks similar.

I think the Mac guys would be able to tell you what you're wanting to know.

Well, the XF, XG and XH used HL carbs, but I have no idea about the numbers....

The roundish diaphragm is for a Mac 73 style carb, the more square diaphragm is for the Mac flatback.

Wouldn't be a big leap to assume the gear sprockets are for the 73 style Mac.

The Tillotson manual for HL carbs says the HL103 was made for McCulloch. The sprockets are also for the older McCulloch.

The round diaphragm could be from a 73, could be 4-30, 47, or 77 as well. The square shaped one is indeed the metering diaphragm from a McCulloch flat back.

The HL 103 was used on some early Super 797 saws, others as well I'm sure but I can't make a specific reference.

51793 is a 1/2" pitch sprocket for the large frame McCulloch direct drive saws.

The sprockets look like they are for 9/16" pitch chain.

Would the 103 fit a 125? If so, would there be any advantage over the SDC that's on it now?

I just so happen to have a 47
