No, just came across the photo and it made me wonder if one of the military applications was a water pump. You never see the Type 133 in the actual application. I know there has been mention of them being used in target drones as well, who knows...
Welcome to the forum Ray, you’ve come to the right place. Can you post some photos of your Tiny Tiger? Send me a PM and I can probably help you with a carb diaphragm and gasket.
Never seen one of these Kenco pumps in the green. Looks like a Type 133 military engine, unless someone used a Type 133 to replace the original engine on the pump. It looks like it could be original paint but it’s dirty and hard to tell for sure.
Thanks! I just don’t have any good tools for cutting, bending and no welding. I was kind of fortunate when I was in MN there was a large metal store and they had a misc cut bin. That’s where I found a couple of the 3/8” thick plates already cut to shape- I knew they would come in handy at some point.
I’m hoping to put it in a boat some day- it’ll be a nice shelf piece for now. I tore it apart yesterday and getting it back together today/tomorrow so it’ll be ready when the right boat comes along. After opening it up I don’t think the engine has been run much at all. There was no carbonization and all the little plastic bearing cages looked new.
I’m still kicking myself for not buying the O&R boat I had a chance at when I was back in Minnesota. I need to figure out what all bits and pieces I’m missing - like drive shaft, collars, etc.
Very cool, I bet that would be a fun boat to blast around a small lake or pond. I tore this one apart this afternoon. I didn’t see anything out of the ordinary and it has the usual feather vane. I’m curious what the rotary valve looks like that’s in your engine. Do you have any photos?
I think I have most of those other parts. Many of the other items are for smaller boats and not the 1 hp O&R, or maybe a smaller O&R engine. Yes, the brochures are mainly for other smaller engines as well and are 70s era. By the way - I didn’t pay that price...
( you know if you wont that to run you will need to install a fuel line )
Still trying to decide if I want to try to run this one.... I’ll need to do a little work on the spark plug wire as well, has a couple cracked sections.
The seal in your first photo can be purchased from McMaster Carr, it’s just a square o-ring.
Like Wallfish indicated standard small engine filter foam will work. I usually stuff it through the hole and then use a pic or screw driver to work it around until it expands into place.
Definitely don’t remove it! It looks roughly like 1/16x1/16 in the photo.
I can probably get a square o-ring from McMaster Carr, although it might not be squishy enough.
I just took another look at my induction housing and it looks like there might still be enough of that seal in there. It is compressed and formed in place so I think I’ll leave it be.
Do you have any way to measure the thickness of that black sealing ring? Mine must have gotten squished and deteriorated over time. The exhaust collector has a similar material/seal. I didn’t remove the seal from the collector, leaving it on there and hoping it will seal up enough for the shelf...
I finally got the entire engine dismantled. Some interesting observations (at least to me anyway):
the engineering on these early engines is exquisite, noticeably different from the later versions
this one has metal roller bearings throughout, and some of the cages look to be bronze, very nice
piston has 3 large rings
no rubber seals anywhere and no gaskets inside- all the machining seems to be really tighten tolerance (no feather vane gaskets and no little rubber induction case seals. The only thing that resembled a seal is some thin black coating stuff that looked like a thin layer of gasket maker where the feather vane gasket would normally go
connecting rod uses a pretty cool two-piece roller bearing that is made of aluminum
the points are a little different too and have a slotted piece that catches the copper tab
It’s starting to clean up nicely. I can tell by the piston, cylinder and the internals that this thing hasn’t been run much, zero carbonization or anything, just a light coating of dried oil/gas varnish. I’m pretty certain I’m the first one to open this one up, didn’t see any signs of others getting into it.

Looks like Wallfish has you covered but I can help on the next one.
There are a couple on eBay as well.
