If the exhaust collector will not move, the cylinder will need to be unscrewed. But make sure the piston is free to move before trying this, as the con-rod will break if the piston is stuck.
 
The engine maintenance manual gives details on making a cylinder removal tool.
The instructions given are to make it from a piece of flat steel 3/16" thick & 1" square, with a hole drilled in the middle for using a screwdriver as a "T" handle.
 
I made one from a piece of steel & bar found in a box of offcuts & salvaged bits in the shed. I didn't bother to make it 1" square though, I only squared up the ends and drilled the hole for the bar.
If the cylinder is very tight I usually use a vice to hold the engine crankcase (use wood or similar to protect the engine from the vice jaws) and use an adjustable spanner to turn the tool. You will probably need to replace the gaskets if you remove the cylinder to prevent leaks. Also make sure that the slot in the top of the cylinder lines up with the crankshaft or is at 90 degrees to the crankshaft when reassembling.
 
Here is a picture of the cylinder removal tool I made.

The Nichols generator was featured in the Jan 1963 edition of Popular Science magazine;
https://books.google.co.uk/books?id=myADAAAAMBAJ&pg=PA157#v=onepage&q&f=false
 
Both the Nichols & Creme Lure generators had 110V AC outputs as standard, some also have 6V & 12V DC outputs as well. According to the article linked above, the batteries inside were used for starting.
 
David

Thought I should start a thread for the Creme Lure generator, as we don't seem to have one.
 
Here are a couple of pictures of the generator in my collection, it's a "super portable power pack" model S made by the Creme Lure Company of Tyler, Texas & Akron, Ohio.
Most of these generators haven't aged well due to the frame/covers and gas tank being made from plastic, the gas tanks are often warped & the covers can crack.

This generator was also sold by Nichols Ind. Inc. of Jacksonville, Texas.
Here are a couple of pictures I archived from ebay.

Talking of surprises, I found this special triple engined Aquabug when doing some research this week, it's rated at 4HP, has anyone got one?

I've finally identified one of the mystery tools from the first post, the engine with the blue frame & guard with a K in it.
It's a Krestronics KGC-3 Charge-A-Lite generator, same outputs as a Tiny Tiger but with a belt driven generator. The article below is from the Popular Science March 1962 edition, which is available online here; https://books.google.co.uk/books?id=OyEDAAAAMBAJ&pg=PA172#v=onepage&q&f=false
I'm guessing it wasn't as popular as the direct drive generators like the Tiny Tiger or Amp-Champ as no complete generator has been found yet.
 

 
There is a much bigger article on this generator in the Popular Mechanics April 1962 edition, the pictures look like a prototype version of it though. Available here; https://books.google.co.uk/books?id=F-EDAAAAMBAJ&pg=PA128#v=onepage&q&f=false

I've been doing a bit of research and have found an early article on O&R engines including some of the first tools available, some of which probably didn't sell very well.
The full article in Popular Science magazine June 1961 edition is available on google books, it starts on pages 64 to 67 & the rest is on pages 208 & 209; https://books.google.co.uk/books?id=ASYDAAAAMBAJ&pg=PA64onepage&q&f=false#v=onepage&q&f=false
 
Here are some of the tools I've never seen before, including a gold separator, a different bike engine kit, a light aircraft tractor, a different design of compressor, a small mower and the smoke jumper (not sure it would have been very effective with that tiny water tank). I'm going to need a bigger shed if I find any of them.
 

 
There are a few more O&R articles in both Popular Science and Popular Mechanics magazines available on google books if you look through the 1960's & 1970's issues linked below.

The May 1972 edition of Popular Mechanics has an article on a minibike with an O&R engine that was converted run on steam power, has anyone come across a steam powered O&R before? Looks quite dangerous.

Webhead and Wallfish on here have spare parts for these engines as well as the new diaphragms for the carb.

No, it was in Florida, I do look on the US site occasionally.
I have also seen two O&R's in Germany in the past, but I don't look there very often, one bare engine and the other was a Little Wonder hedge trimmer.

Another unknown make O&R tool found in the completed listings search on ePay, It has a reduction gearbox driving a pump described as possibly being hydraulic.

Decals received from Machinery Decals today (Thanks Titch ) and fitted...
 

Probably the one being discussed in this thread, the full advert is on the website linked in post 3.
At least two O&R powered Du-Bro helicopters are on youtube, a Du-Bro Shark helicopter which was found as a NOS kit about 11 years ago for $175;
 
 
And a Du-Bro Hughes 300 helicopter;
 
 
David

Definitely interested, is it one of these;
http://www.vrhc.co.uk/rc helicopters/USA/Du-Bro/Du-Bro.htm
From the link it does look like one or two did find their way over here in the 1970's, £195 from a Birmingham model shop in 1975.

Just done a quick count and I have 29 different tools (a few more if you count different versions of the same tool) in my collection, 13 of which have been found over here. There is also quite a lot of engines here too, as well as a few duplicate tools. Definitely still catching up though.

Chemical Metal is a brand of two part polyester resin made by Loctite/Henkel over here, it is probably sold under a different name in the US. The safety data sheet provides all the info on what's in it; http://docs-europe.electrocomponents.com/webdocs/001f/0900766b8001f4d2.pdf

Chainsaw collected today from the Mower Centre, many thanks to John Cruse for the new chain
 
Just need some decals now...
 
 

Second tank collected today, looks good... (original is on the right in first photo)
 
 

I've just seen what it's for, a home-made centrifugal clutch, the other half is on your Fox engine.
 
David

The seller of the parts also had a couple of engines that had been converted for RC model use (boats).
 
Top one is probably a pulley, but does look a bit like the flywheel used on the much older small Ohlsson model engines that weren't used for model planes.
 
The other is possibly an adaptor for the PTO shaft, again for RC model use.
I have a slightly longer one that came with an early parts engine, that was used to rebuild a Tiny Tiger with a damaged crankcase and other missing bits.

Same company that supplied the early drillgine drills.
There was one on ebay UK earlier this year, but as I already have a later yellow drillgine I decided not to buy it.
 
David

It appears that Fox Motori who supplied the 22cc engines for the Turbair Fox also made a backpack sprayer with the same engine, see here: http://www.foxsprayers.it/en/about-us/history/
Also found a parts diagram for the Fox Motori F7 engine here:http://www.foxsprayers.it/wp-content/uploads/2016/12/Motore-F7.pdf
 
A while ago I scanned the Turbair Handbook which features the Turbair Fox sprayer on page 5, it was uploaded as a pdf here;

Certainly looks very nice, it's also one of the rarest O&R tools.
