Landed a pretty cool Lancaster 15SLA chainsaw. Just opened it up tonight so I haven’t been able to dig into it in great detail yet. After a quick wipe down and initial scan it looks like the carburetor needs a complete overhaul. It had been removed and dismantled. Unfortunately it is the style with the little rubber plunger arm and that is missing It’s also missing the carb lever arm spring. Looks like the throttle cable is also broken where it goes into the handle, I won’t know the extent of it until I open it up. Other than those obvious issues and a couple misc. screws it looks to be in really nice shape, the paint is nice and bright and only worn in a few places.
The starter pull handle is also kind of neat. It resembles the 13B handle but has a much nicer taper and is smaller. At first I thought someone might have put a 13B handle on there in place of the little wooden ball but I’m convinced this is the original handle. I saw another chainsaw like this online that had the same style handle as mine.  The air cleaner is also kind of neat and attaches with a 90 rubber elbow/boot.

Thought you all might appreciate this cool photo from 1967 of a guy tapping a Maple tree with a Drillgine.

I'm holding those saw parts hostage for free decals
 
Just sent the box today Clint
Sent Terry's box yesterday

That would make an interesting video.

That’s to hook up the glow plug
Im surprised that you could not tell what. you will need to get out more. 

The guy who didn't take the carb apart and keeps his plug-in air freshener in with his parts.
 

Apparently they made at least one...

Now hold on hew do you think your talking to. My parts are safe and sound in the box were they should be

I can only think of one person that losses thing. Oh ya I think the parts were all there.

Been giving the engine a bit of a tidy up...
 
 

I knew i could get this apart in less then a week

I’ve been hoping for a long time I would find one of these and after months of constant searching I finally hit gold.  Wish it had the cut-away gear box too but I’m thrilled just to have the engine. It needs a recoil spring and pull rope to complete it and of course a thorough cleaning. I’ll have to come up with a cool display stand as well.  It’ll look cool with the recent brochure that also shows this engine.

Cool engine does it run ok or need a little work

I can email some pics of the chip a saw decal with dimensions later today if that helps. Might have a print of one from usedtoolman which might be better to use for duplication but let me know. Depending on cost, I could use 3 decals for the older saw. It was stripped down but never painted

The diaphragm pumps fuel. The tank can be lower than the carb. This is my best guess.
Pulse of the vacuum pressure from the case flexes the diaphragm to pump fuel and the amount of air flow past the jet pulls in the fuel. The needle valve meters the amount of fuel being taken.  More air past the jet equals more suction which equals more fuel. More fuel and more air equals higher rpm. The amount of air is metered by the butterfly valve inside the carb body. The butterfly is metered by the governor vein. The governor vein is metered by air flow from the flywheel speed. There are also reed valves inside the engine which control the vacuum and positive pressure of the piston moving inside the case. It's all in the precise timing of the components. At full blast it all happens at 6300 times a minute or 105 times a second.
The choke helps with starting to pull fuel with the vacuum from the case because you can't pull it fast enough for the air flow past the jet to do it. Same for the primer button, it's a bump for the fuel for starting only. But once that spark happens in the chamber with fuel in there, pow, things move quickly.
Hope this helps.
 
 

Ha- I didn’t even look at closely at the photo to see what was on the decal, silly me.... I like the TED 232 drill so knee jerked at what this might be.  Pay no attention to the guy in the desert

The carburetor operation is explained in detail in the manual;
