factory

Could be either, maybe original adverts could help or add to the confusion, if any ever turn up. David

The spacers were made to approx 11/16" length, the wide washers are to prevent damage to the cover (two used per screw). I had to order more screws (#6x32 2" long) as the first ones I ordered were too short, a set of these were sent to Paul for his Aquabug restoration. David

If only the people at work could keep their fingers out of the large gears when taking apart axle mounted gearboxes too. David

It's all down to the fonts used, at least John's picture confirm what you saw (no pun intended) on yours before restoration. There is also this smaller decal on the red version of this chainsaw, again not very clear. I have to say Paul Bunyan/Bunyon chainsaws are a PITA to research information about due to the amount of other things with the same name. David

Will check them at the weekend, I ended up making my own from brass tubing as I couldn't find anything suitable. David

Exactly as it would have been in the 60's, as shown in this Speedy Sprayer brochure (no O&R's present). David

Nice to hear you found more parts from the trimmer, I have some of the small parts for those but sadly no cutter head, I intend to try & build one using a spare engine, will need to make a lot of the larger parts and see if I can find a modern cutter head that could be used with it, this is a long term project of mine. It would be helpful to know the length of the aluminium tube(s), please could you let me know the size. I do have this parts diagram for an earlier variant of the trimmer (known as the Power Whip), I can't see a trigger control on this version, but the diagram may help identify more parts you may still have. Forget to mention before, looking at the first three digits of the serial number I can tell you that the engine from your trimmer was made in April 1977. David

@Webhead Do you have a before picture of the bar from your chainsaw, I'm yet to see a clear enough one to tell if they spelled it incorrectly originally on the bar, certainly the small round logo is spelt Bunyan. David

You should have an email with the two page brochure attached. David

John I still need to complete quite a few unfinished projects here, before I make a start on that nice trimmer (or take anything else apart), maybe I should add some pictures anyway. Nice find with the manual and EP Barrus advert, I seem to have the matching "illustrated literature" for that Orline hedgetrimmer. David

I thought I had uploaded that one but turns out I haven't yet, it's from a two sided brochure leaflet from 1963 (the source of my avatar image), I have a four page brochure from 1963 plus some other bits to add to the "manuals sticky thread" in the future. Would you like me to email you a high resolution image of that page? David

Ohlsson & Rice Compact engines appear regularly on eBay, you shouldn't have difficulty finding another suitable engine for a boat. As well as being incorporated into many different tools, the engines were available for anyone to use for making their own tools or for powering models etc. Some O&R engines can also be found with water-cooled cylinders for model boat use. David

The old ratios used were 11:1 till 1963 then 24:1, we have been using 32:1 with modern mineral based 2 stroke oils. I've only seen a couple of these 1HP engined versions, the larger 1.6HP 20A engined version is only slightly more common due to eight boxed ones appearing from one seller in 2018/19. David

Here is what the Groomer Estate 400 in this thread would have looked like, sorry the picture isn't very good quality, I don't have any original documents for the majority of the AEP powered string trimmers. David

Thanks Clint, I'm a bit surprised no-one has added a link to here in that thread. David

The condensers are usually fine, cleaning & adjusting the points should sort out the spark problem. You would probably find an RC carb much better if you plan to use one of these engines in a boat. What do you plan to do with the rest of the unit? they aren't exactly common. Usually I find a small gas blowtorch more than adequate for heating up seized fasteners to free them. David

If only one side is damaged then I usually put it in my spares, then later re-use the good half when I find another with the same problem. David

What about the CAD files then? The carb diaphragms we supply were all cut by Eric "the gasket man". David

Do you have a link to that one, or save any pictures? David

Finally checked the engine type on mine, it's also a type 112, sn #018611. With all the mention of replacing plastic bearing sets with the metal versions, I try & re-use all parts where possible including those plastic cages if no damage is obvious, remember there is a finite supply of spare parts for these engines. David

Look for the other version powered by the Series 20A engine too, a seller had a pallet load of them which "were" all new-old-stock till the seller ran them all , I did try and get them to list one they hadn't run but got no-where with them so didn't buy one myself. David

I seem to have saved the ePay pictures of your saw, interesting to see what looks like "Bunyan Saw" on the bar next to the "Chip-A-Saw" logo. David

Good to see it back together after all the trouble with that gearbox, hopefully no bits left over, nice & shiny too. David

Sounds like some tools over here, they used them till they were worn out, bodged them & used them again till they were completely trashed. David

I think the reason they sometimes appear is explained by the price list, they discontinued one older backshaft (with no keyways) to reduce parts inventory at the factory and to keep the other backshaft (with keyways) available for all older engines with or without the clutch. David
