Cox (an O&R competitor) made both model engines & the Series 140 engine found on that chainsaw (Beaver), they also sold a bike kit (Bronco), more info here (scroll over half way down); https://www.mh-aerotools.de/airfoils/cox_specials.htm Roper acquired the rights to the Cox Series 140 engine and re-branded the engines & tools. David

There are a pair of O&R chainsaws in this estate clearance auction in New Castle, IN , maybe of interest here and keep a watch for future auctions at the same location as this is the 5th sale they've had ; https://harmeyerauction.hibid.com/lot/63695100/chain-saws--6-in-lot-/?cpage=4&q=&ref=catalog Previously sold Tiny Tiger large tank version for only $38. https://harmeyerauction.hibid.com/lot/58406769/tiny-tiger-generator-in-wood-box/?cpage=3&q=&ref=catalog Cutaway engine for the bargain price of $62. https://harmeyerauction.hibid.com/lot/62247722/ohlsson-and-rice/ David

Nothing unusual I can see with the recoil, it's a Series 13B engine, the chain cover & air filter are different to the Orline versions. David

Found this by accident searching for other chainsaws. Indian branded O&R powered chainsaw on flickr at a show in Milang in Australia; David

Australian Mobilco chainsaw with the TAS motor, could it be a licensed copy of the Petro Chug-A-Saw? http://chainsawphotos.blogspot.com/2005/09/mobilco-vintage-chain-saw.html Note: there are some differences, such as the chain oiler being part of the handle and the handle also has Mobilco cast into it instead of Petro. David

Stupid question, do any of those match properly the size of the original fuel line for O&R's? It's not normally a problem, but with at least one tool the new stuff is too big (externally) to fit the hole in the side of the tank. David

Look familiar? Can't help thinking the tank needs rotating 90 degrees if it's permanently attached to a truck as shown above, also notice who sold it. David P.S. There are about 12 editions of Desert magazine from between 1961 & 1963 with O&R powered products, I need to get links added to the sticky thread as PDF's are available for all of them.

He was complaining how expensive it was in the video, not sure about that as there is cheap tubing on ePay, but not necessarily available in the size you want. David

Well I seem to have two sets of pictures for this winch (it got sold twice on ePay), spot the difference!! I wonder what happened to the small chain guard? And what happened to the decal? David P.S. it made slightly less the second time it sold.

Another early TAS chainsaw (model P73) complete with the original advert, on French chainsaw website; http://collectionneur-tronconneuse.fr/p73#more-92 David

I had seen that one before but don't think I posted it, there is a decal (BHV Bazar) on the other side of it that could be the model/brand/shop that sold it? http://collectionneur-tronconneuse.fr/compact-3#more-1085 I assume you had a look at the Butterfly chainsaw too. http://collectionneur-tronconneuse.fr/p73#more-92 David

Thanks Paul.

Laser cut!!! , I had to square up that thick off-cut of steel for my test/display stand by hand using a hacksaw & file. David

The Model J seems to be one of the more common gearbox models found, PTO output is 900 RPM. It's definitely used on the Halicki Skateboard/Toby Cart, the 1964 DIY Tom Thumb scooter/mini-bike project and possibly the early Petro mini-bike (can anyone confirm). Sorry if listing those has just up the selling price for the Model J. David

Still haven't seen any-more of these K.C. Wiggins Champ generators apart from the Fox powered one and the O&R powered version I have; I never noticed before that the fuse positions are swapped on your generator, are the fuse ratings labelled? David

Yes it is, I've been meaning to add a thread about it but never got round to it, should have time now. It will be fine, the engine on that display stand is only attached on one side (some tools are too, such as one of my hedge trimmers) and it's been to engine shows on the stand. That engine was also stuck when I got it, the oil in the bearings had turned to varnish. David

Maybe you could make something like this test stand I made a few years ago, it never actually got used for testing anything as it quickly turned into a permanent display stand for this engine, going to need to make another eventually. By the way I noticed your sectioned engine is missing something, some filter foam for the air cleaner. Also I had a thought overnight having remembered seeing a sectioned engine being slowly driven at a local engine show (many years ago), a slow low voltage DC motor (3-4 RPM) could be used for this. David

Apologies I forgot to add the Variac before the welder to control the glow plug current. David

Complete opposite here in the UK, massive queues to get food in some places & too many people close together. I'm now off work till Easter, someone finally had sense & closed work as distancing just wasn't working in most areas, plus passenger train parts must no longer be key work. That was impossible for me, work don't like people looking on their phones, plus many cameras are now watching & being used against us. David

Strangely familiar yes, I think I remembered to fix the starter before I sent it your way. David

Original service procedures for taking apart & repairing the two older style starters can be found in the manuals sticky thread in Section 2; The rivet does not hold the reel or spring in, it's for the reel bearing and that doesn't need to come out to service or repair the starters. I hope were not too late. David

Yes definitely Fillister head screws, @Webhead has helped with the Phillips type used on most engines, I've also found a UK supplier (Accu) for the Slotted type used on the early engines, I ordered a couple of samples of chemical blackened versions with my last order from them. McMaster Carr have stainless steel Phillips Fillister head screws in sensible order quantities, they also have Slotted version in both zinc plated steel & stainless steel; https://www.mcmaster.com/fillister-head-machine-screws David

Hope it works out, I didn't make an offer as I've spent too much recently (that minibike mostly), plus the £ has dropped in value a lot (TP will be worth more soon ). David

I'm not sure about the tank as it hides some of the cut-away parts, plus there is nowhere for the condenser to attach. Your not kidding, first one we've seen for a very long time. David

Looking very nice and well done for saving the original decal. David
