The side mounted needle valve is original as it's an earlier style carb, there should be a #10x32 screw (half inch long with lock washer) that is missing from yours. Webhead on here sells replacement carb diaphragms, the originals have often gone hard & brittle, it's rare to find one that is still flexible. Here are some pictures of the carb from my Petro Chug-A-Pump that I restored last year. Check that you have all the bits shown in the first picture, the small roller & ball bearing are often missing if someone has been in there before. The starter spring can be repaired by heating the end section with a blowtorch and bending to the correct shape with a pair of round nose pliers, make sure that it goes back in the right way round when reassembling, as shown in the second picture below.

That's interesting to know, mine dates from the mid 1960's, so it could be the Bridges drill. There are a few Drillgine drills over here too though. I've never been able to find anything searching on the web, google tries to change the spelling of Mota which doesn't help. David

I bought one of these drills earlier this year, here is a scan I have done of the manual that came with it. The condition isn't great, but manuals rarely seem to stay with any of the tools. Also there is no mention of Ohlsson & Rice anywhere in the manual, instead Bridges refer to the engine as the Mini-Mota.

Welcome to the forum. Are you sure the 120V output is DC? Or is it a Champ generator, as they have 12VDC, 115VAC & 115VDC outputs. http://myoldmachine.com/topic/1386-amp-champ-generator/ The model 400 featured in this thread doesn't have a low voltage output. Have a look at the pdf I posted in this thread if it is a Tiny Tiger, although it doesn't list a 120VDC version. http://myoldmachine.com/topic/2968-tiny-tiger-arrives/#comment-33893 David

Very nice restorations, I have a few in need of a repaint, also its good to know you can get the other decals too. David

Is the square backplate aluminium? it almost looks like asbestos from the pictures. Also it looks like it may be difficult to attach the bottle. David

Definitely the only fairly complete one I've seen with the later starter, I do have the engine from one in my collection, it also has the mesh debris screen. Never seen one fitted to anything else though, must be something Turbair added. David

My PC has Windows 10, I usually use Firefox for the web. This site is working OK with Firefox and the other two browsers (Internet Explorer & Edge) on my computer. If something goes wrong I usually try the other browsers to see if they work or if the problem is somewhere else. As Karl says, posting a screen capture and what you are using (the operating system and browser) to access this site may help with identifying the problem. David

Here are some pictures of my Orline Challenger Mark IID chainsaw, it has the larger model 20A engine, with a different (early?) starter housing to other model 20A engines I've seen. I had intended to take some better pictures, but started work to find out why the fuel line was missing, after looking at the carb to identify the type for another forum member. To get to the fuel outlet on the tank requires removing the engine from the saw frame, unfortunately I'm currently waiting for a socket to arrive to remove the last part preventing engine removal, the compression release valve. Everything else has either been removed or loosened ready. I also found the missing (when bought) carb choke lever screw stuck to the flywheel magnet! I managed to obtain maintenance manuals for both the model 20A engine and this chainsaw, they have been scanned & turned into pdf files and added to the manuals thread. David

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

Nice pictures, what make is this pump? I've not seen one like that before. David

They are definitely a lot rarer, I certainly couldn't find pictures of any others on the web, although there were some on the old forum but I never saved a copy of them. Here is the only other information I could find, from magazines scanned by google; David

Thanks for reposting the NIAE test report, they certainly had a lot of problems the the early engines they tested. I found a test report made by the U.S. Department of Agriculture in May 1964 for the Paradox pump online recently, I posted it in the Electro Flow pump thread, but here is the link again; http://www.fs.fed.us/t-d/pubs/pdfimage/64511303.pdf I've downloaded a copy in case it disappears the the linked site. Even though I only took three O&R tools to this years "1000 engine rally" over here, they certainly attracted plenty of interest and there was even a few people that remembered using them in the past. David

This original Ford manual for the model 20A chain saw has been on my ebay watch list for a long time, have you got it?; http://www.ebay.com/itm/171817653659 David

Welcome to the forum. Your engine is a model 13B (1HP), the full model number should be on the cylinder plate. Here is a carb diagram, although it looks like your carb is a later one with the rubber part on the lever, instead of the ball. Ohlsson & Rice Type 210 Carb Diagram + Parts List May 69e.pdf.pdf I can't see the clear valve that goes with the red gasket (item 6 on diagram) and the choke lever has been broken off & shortened, there should be a ball in front of the spring. Webhead and Wallfish on here have some parts for these engines, Webhead also makes replacement carb diaphragms. There is also a carb repair thread to help with rebuilding these here; David

Found the engine diagram for the Model 20A-274 in this thread, PM Wallfish as he has the original. David

Correct, they are Orline (O&R) chain saws badged for Ford, I'm sure someone said they were given away with new Ford tractors, O&R also made badged versions for Sears. (Edit 14/5/19: according to service bulletin S-E083 they were sold by Ford tractor dealers.) Here is my Orline Challenger Mark IID, I will put some better pictures in a new thread. David

Your engine is model 20A-274, so there are probably some slight differences to mine, I suspect the starter mechanism will be different as mine has the early type. I took the carb off mine for a better look at the model number, the carb fitted is a Walbro HDC6 (I've corrected the previous post). Also I have found the first error with the model 20A maintenance manual, as the carb has a right angle fuel inlet and the manual shows an incorrect carb model no. below the picture. Here are some pictures of the carb and the other parts you may be missing. I thought mine was complete but it seems the fuel lines to the carb are missing. The tank outlet is hidden under the starter mechanism housing. David

Looks like my Challenger Mark IID chain saw is fitted with a Walbro HDC6 carb, I will have to double check tomorrow as the picture isn't very clear. Are there any other bits missing? Also is the engine type the same as mine, 20A-258? It should be on a plate like this. David

A slightly more unusual Tiny Tiger generator arrived a couple of weeks ago, it's a Model 400 from Gadco Electra. It doesn't use the permanent magnet rotor found in the Model 300, instead it uses a wound armature & carbon brushes, same as you would find in older generators & motors. The output is 115V DC 400 watts only, there is also no low voltage output provided. Has anyone else on the forum got one of these or any pictures of a complete one, as mine is missing a few bits? I did find a article featuring both the Tiny Tiger 400 generator and a Safe-T-Products brush cutter that also appears to use the O & R engine, in the December 1962 edition of Desert magazine pages 6 & 7, a pdf is available from the swdeserts.com archive here; http://www.swdeserts.com/index_htm_files/196212-DesertMagazine-1962-December.pdf David

Definitely louder than any other engine I've heard at any of the local vintage engine shows. I've always wondered how much difference this exhaust makes to the noise. You've also reminded to get this vintage sound level meter fixed, I bought it more than a year ago and still haven't got round to it! David

Welcome to the forum. I don't have any Ford documents, but do have the O&R diagrams & maintenance manuals for the equivalent Orline chain saws, I will scan them when I get time. Any chance could you post some pictures of your Ford chain saws. David

Welcome to the forum Bernie. Send either Wallfish or Webhead on here a message, they both have spares for these engines, Webhead also has replacement diaphragms for the carb. David

Very nice displays, I displayed a few of mine earlier this month at the Peover Game Fair. David

Seems that the Teles Hedge Trimmer maybe based on the Gibson Hedge Clipper, which is featured in the January 1963 edition of Desert Magazine on page 9, a pdf is available from the swdeserts.com archive here; http://www.swdeserts.com/index_htm_files/196301-DesertMagazine-1963-January.pdf And it was also available in the US as the Paramount Hedge Trimmer, picture taken from ebay.
