Thanks JustO&R - nice find! Is this a different seal than the one you had to modify the retainer ring? I’ll be on the hunt for one, that seal needs to be replaced on my engine. Someone before me installed it backwards and it’s pretty worn out.

David, These are great, thank you for sharing the service bulletins. Now I at least know what to look for, albeit likely impossible to find. It’s interesting that they went to a non-replaceable seal on something that is a wear item and relatively easy to fix with standard seals. I wonder how much of a difference it would make putting a conventional seal in there. Nice photo by the way, you can see your seal much better. I couldn’t get the lighting right on mine. I have the blue seal like the one you show. Thsnks!

It didn’t appear to be anodized. You were right about the exhaust collector set up. Has the red gasket and the one spacer. The induction case also had the o-ring seal. The front end of the induction case has a different type of seal than I’ve seen before. It appears to have a rigid metal core - and it doesn’t look like it can be removed without destroying it. It needs to be replaced but I don’t think I’ve seen any like this before. I’m thinking the gas tank probably doesn’t have anything special inside it so I’ll gently probe with a piece of wire and see if it will start to clear up. There is an original in-line fuel filter that is external to the tank and goes between the tank and the carb so I’m hoping there isn’t any full line or other filter inside the tank tube. Unfortunately the piston is pretty scored up. The cylinder walls don’t look too bad but something got in there and really gouged the piston. This newer engine also has a different type of bearing on the main shaft inside the induction case.

Yeah, I think so. There’s 40+ years of oxidation and nasty fuel residue and junk but with a little work it’s cleaning up pretty well. Of course the nipple of the gas tank is clogged. Any guesses as to how this might be set up inside the tube? Any chance there is some sort of rubber two-way valve like on some of the later carb inlets?

Decided to clean up a couple sections just to see how this might look later...

Thanks David, good to know!

Yes, I can’t remember what O&R engine it came off of but I think I can make it work for this mower-Trimmer.

Success, got the spindle free from the shaft. With the crankshaft being so loose there was about 1/16” of play between the front face mounting plate and the back edge of the spindle. I notched a large washer and slid it into the gap. Then when I smacked the opposite end of the spindle it finally broke free.

Hopefully he’s still drafting up the Chip-A-Saw decal as well

All the important pieces look to be there. I won’t know until I can get the engine apart but it seems it might be missing a couple pieces on the exhaust collector. I don’t see the usual spacers or gaskets that sandwich the top and bottom of the collector. This spindle shaft is really being cantankerous- it just wont let go!

Starting the tear down of the Landscaper 600. Went ok for the most part but the main spindle won’t come free from the crankshaft. It has a single threaded screw that attaches it to the end of the crankshaft like most engines. It is really seized up on there. I tried all the usual tapping tricks but still no luck. I also noticed that the entire spindle and crankshaft are super wobbly and loose. I’m hoping it’s not broken inside the engine. The bearings are most definitely shot, hopefully the shaft is not cracked. Not sure what to try next to get this spindle off. Definitely going to take some serious cleaning...

Cool, thanks for adding the photo, this conversion to an O&R was meant to be

Thanks! Yeah, the O&R looks right at home on there- this was a fun little project. Hoping my son will cherish these things some day.

Ok, here’s the little project I’ve been working on for the last couple weeks. I’ve been wanting to make a small lawn mower/trimmer with an O&R and I had a nice 133 military engine that needed to find a home. Thanks to Terry@Just O&R, he was able to hook me up with the perfect vintage mower - it was exactly what I was hoping for. This one is a 14” Sensation, perfect size and design style for the O&R. It’s not 100% done yet but I couldn’t put off getting some photos posted. I’m still working on the actual trimmer concept and plan to go with more of a weed eater head set up instead of a mower blade. I plan to use the starter cup off a vintage Pioneer chainsaw and drill three holes so I can pass through some pre-cut Trimmer lines with end-stops. I’ll figure out a good way to secure the cup to the spindle shaft. I also added a stop button to the back plate similar to a few other O&R tools I have. I’m also finalizing a short throttle cable, doesn’t really need one but thought it might be nice. After a lot of hunting I ended up finding a cast aluminum boat chair pedestal that made the perfect adapter plate to mount the engine to the mower. I also had to swap out the normal Type 133 mount with one that has a couple more inches in height. This was needed to get the right clearance for the gas tank. Just a note, the early style Drillgine gas tanks don’t mount to the newer style engines and I had to make a couple slight mods to the casting on the case to get all the clearances to fit right. Here is the before and after...

That turned out nice, sounds really good too!

Those are really cool decals! Where will you end up getting some made?

Looking good, it will be fun to see that thing run - it’s a beauty!

It looks like this engine model is CCW, that’s different from the average O&R isn’t it? I had thought about that too when I was going through mine but then decided to leave the grills alone. I think in this case leaving in all the character looks great.

Yep, cooking up a little something - hoping it won’t be too much longer. Made some good progress today... I’m still impressed that these little engines can move an adult, fun watching you and Terry make tracks!

Impressive, that’s some decent power and speed you’re getting out of that thing. Love the videos! I’m in the middle of a couple projects and need to get them done so I can mess with the fan. I may poke around in the garage and see if I can find something suitable for a backpack harness. The throttle control is built into the fan handle so that’ll take some rigging too.

Ha ha, now this is getting good! I’ve been looking forward to seeing this all day! That Toby Cart looks fun and sounds good too- nice work getting it all fixed up. Cracked me up, too funny! You guys are awesome! That fan bicycle concept looks interesting. Maybe I can rig up some backpack straps and give it a go sometime.

Same one. I had expressed serious interest in the one on Smokstak when I first came across it. I checked in with him again and we were able to make it happen; he’s a really great guy.

Nice! That’s awesome John! Who needs a Harley when you’ve got one of those Yep, time to see Terry launch himself down the driveway! By the way, I must have hit rewind 50 times watching that - too funny

Definitely, I think most of the content in mine is mid 1960-1970s. I haven’t gone through it yet in detail but there are a few master parts list that show part number changes so those are nice.

I acquired a really cool Master Service Manual. It has quite a few service bulletins and good info on a number of engines and tools so in case there is something missing in the manuals thread maybe it’s in here...
