Love the use of 3D printing to prototype the shape. I’ll try to take a look and see if I have easy access to one of these springs. Not sure if Wallfish might have taken some measurements during his experiments. The legs need to be long enough to clip over a small metal Rod that sits in the recess.

Picked up another Lancaster like yours David. Super dirty but should clean up pretty well. It was missing the air filter but fortunate I have one from an earlier junker saw that I got a long time ago. It’s also missing the wire to the toggle switch but that’s an easy fix.

Picked up another Lancaster that might need a cable if you still have any with the black sheath.

I still have a few diaphragms but not the whole carb gasket kit. Never thought to measure the points rod, I should probably start doing that on the engine rebuilds...

Almost, I have everything ready to assemble and then came across another one. The second one was in better shape and I got it running. I’m missing a couple parts on the first one and it also had a damaged handle and is missing the snorkel. I ended up having to make my own snorkel for the other one. Yep, both are the AS400 models with the Tillotson HS carb. I’d like to have one of the later 650 models but $1399 is a bit steep. These are really cool scooters, with summer coming on I’m anxious to give it a try.

Here is a points push rod: https://www.ebay.com/itm/362975352520?hash=item54830456c8:g:9QgAAOSwG5ZenZUz And a complete carburetor gasket and diaphragm kit: https://www.ebay.com/itm/114353640518?hash=item1aa0021446:g:1zoAAOSwIGhgOwOk The carb lever springs are much harder to come by. Wallfish was able to replicate one pretty well. I’ll take a look in my spares and see if I might have an extra used spring. If you can find some thin gauge spring steel, like from a feeler gauge or something maybe you can cut one with tin snips.

I was toying with the idea of making a military version of the Kenco pump... still noodling on it.

Just a thought. The carburetors look similar to those used on some of the old Tanaka, Echo/Kioritz, and Shindaiwa engines. Maybe there is a float that is similar in size. For example, check out e-replacement parts or parts tree online and look up Echo PB-202. It has a similar float design and float bowl, maybe you’ll get lucky... Here’s a vintage Kioritz float - are the measurements close? https://www.ebay.com/itm/Vintage-NOS-Genuine-Echo-Kioritz-Float-P-120-133-0111-0/292981446733?hash=item44370e184d:g:Z-oAAOSwYyVcdEeD Do you still have any of these?

I asked about a Buy-it-Now offer on this listing but they weren’t interested. Looks like they got a buyer anyway.

Has anyone come across any other photos of a military version of his pump?

Wow, nice find Paul! That was a steal at that price.

David, This is fantastic! Thank you for taking the time to take all the detailed measurements and photos of the handle.

David- thank you for the photos - those are very helpful. Yes, I was very glad to see the decal still on the tank. It’ll be fun cleaning this one up!

That would be great! If you do decide to give it a try let me know if it turns out ok and I’ll compensate you for it. It looks like there must be a couple flat sections that bolt to the handle section.

Unfortunately I don’t have the tools to make the bender. Any details on the dimensions, circumference?

Finally had the chance to add one of these to the collection. It’s too bad it’s missing the circular handle but it’s still super cool. The tank is pretty dinged up and it’s been used over it’s life. Overall it’s in ok condition, can’t be choosers... They seem to come up so rarely that I figured I better jump while I could. I missed out on one of these on eBay a couple years ago that was in incredible shape and went for a bargain. At that time I had only been collecting for a couple months and had no idea how rare they were. If anyone comes across an extra handle, please let me know and I’d gladly buy it. Or, if someone has a good way to replicate one I would consider that too.

Good to know- I’ve tried both directions and can’t get anything to thread but I’ll take a close look.

Excellent, thank you for all the info David! I’m hoping I can make this engine work, assuming I can re—thread the gear. Still amazes me how much info you have access to for these O&Rs.

In case anyone is curious what the inside of one of these compressors looks like. The diaphragm on this one is slightly deformed in one spot. It’s surprisingly pliable and looks like it should work ok if air doesn’t leak past the deformed area. I might try to make a new one or I might just leave it, not like this thing will get a lot of use.

Excellent - thank you!

Great, thank you. My hole pattern might vary a little anyway depending on what I can come up with for a gearbox so no worries if that’s tricky to get.

Paul, Is it possible to get the dimensions for the gearbox mounting plate or now that the unit is all assembled I’m guessing it’s probably not very accessible.

Well, maybe some good news. I went through all my stuff and found my Type 150 engine. It has a gearbox with the PTO flipped. It also has an unusual spacer in place of one of the normal legs that attaches it to the engine. This leads me to believe I might be able to rotate the whole gearbox to point in the upward direction vs down like on the chainsaws. I’ll have to pull it off and try it to confirm. If it rotates ok then this might end up being the engine I use for the compressor project. I’ll scrounge up a different gas tank. This engine looks like it might have been set up on a trimmer or something. I also found a shaft that might work. Bad news is when I went to check the fit to the gear I found that the inner threads of the gear are stripped. Not sure if it can be re-threaded but I’ll have to give it a try. I’m not out of the woods yet for the gear and shaft.

Interesting, wonder if they made this as more of a universal base to allow for different power setups. I forget what type of electric motor was on this particular one. It saved another $25 off the shipping by removing it. I’ll also have to make the mounting plate that the gearbox attaches to.
