OK thanks for checking, sometimes they did add dates and sometimes didn't. This is my later 13B Grow Gear trimmer, the handle is different but it has the same plastic gas tank. The earlier Paramount (re-branded Teles in the UK) hedge trimmers have a very similar gearbox & cutter assembly, but use the vertical round gas tank. David

The only mention of Type 150 is in the 1965 parts diagram & list. I've seen that style of gearbox & tank used on a hedge trimmer, but can't confirm that yours was from one. David

I save the shafts from any broken electronic gadgets I take apart, cassette players are just one example of something that may contain these, here is a random picture of a cassette player mechanism I've recycled, full of little parts that can disappear under the bench. Here is one I made earlier (from a cut down shaft) fitted to the carb diaphragm bowl. Model engineering shops would have suitable diameter rod too. David

Can the diaphragm disc not be straightened? Later carbs had a smaller flat disc glued to the diaphragm. I've used shafts taken out of broken cassette players to replace the roller and cut them down to fit. I thought Wallfish was looking for the diaphragm arm for you, give him a chance to look through his spares. David

We would never find anything that fits over here, everything is metric over here these days, thankfully mine still has the gas cap. David

You might not have seen it yet, but they changed most parts of this type of starter assembly in July 1973, I mentioned the redesign very briefly in the 13B recoil spring thread last year; https://myoldmachine.com/topic/4816-ohlsson-rice-recoil-spring-for-13b-engine-starter-rebuild-guide-post-9/ Note some parts are not interchangeable such as the starter reel & the housing for that reel. They could have kept inventory of both starter spring, but in business costs are reduced by removing similar/duplicated parts from the warehouse. David

I will update the thread title to sold. David

Looks in very nice condition, it's the slightly less common & later large gas tank version. It's usually the little rod, ball bearing & U shaped spring that go missing. The engine on your Tiny Tiger dates from 1968, so unless the carb has been replaced it should use the standard arm & ball bearing check valve, those U shaped springs only have a slight bend & are usually reusable. Typical late 1960's carb diagram & parts list below; The plate? Is this the one attached to the cylinder? If it is someone has bent it to get the carb needle valve out without removing the carb from the engine. David

Nice, looks to be some service info between the very early one I have and the more common late 60's service folders. Is there a date on the engine manual? the 1961 version I have could be very similar to that one. Yes I have one and @pmackellow does too, but they are both later Series 13B powered versions. David

Please post some pictures of the carb so we can identify the type & advise what parts are missing. Also don't forget the clean out any old crumbly foam from the air cleaner/filter and check out the carb rebuild thread if you haven't already seen it. David

Now down to $150 with make best offer. https://www.ebay.com/itm/114006353971 David

They updated them in 1963 to use all metal parts for the bearings with no change to the dimensions, the slotted con-rod is used with the all metal con-rod main bearing as previously mentioned, no need for guessing. See both points (b) & (c) in the NIAE test report below. Later engines increased the diameter of both the crank-pin for the con-rod bearing & the big-end bore of the con-rod, hence the need for 16 rollers instead of 13. David

Looking at the pictures & description it looks to have a quick release mechanism & two pins for the two main parts, same as modern bikes do for some parts. David

They are only noticeable from the MOM homepage in the latest topic column, unless you regularly check for sale & wanted threads. Now moved to the O&R section. David

I only have parts lists for O&R made (& rebrands) chainsaws and the later 6 digit part numbers don't give any sizes, also I can't confirm that other manufacturers used the same chain & sprocket as O&R did. David

Not sure, but it was indeed shown in three parts. David

That is the later one I was referring to above (post #43) that uses more modern type seals, they also changed the induction housing one to a similar type but made it non-removable in the process. David

Yes. 1/4" pitch chain and a 12" bar. Manual oiler, seems all of the O&R saws are manual. Mine is missing the the plastic knob So these have a different pitch chain to the more common O&R/ORline versions (& rebrands or these)? Some of the later O&R/AEP powered chainsaws did have what they claimed was an automatic chain oiler, from old adverts I suspect they just incorporated it into the throttle control. David

I tried many different seal suppliers but couldn't find anything like the originals in shape, also modern seals seem to be a lot wider. O&R did change the seal & the bearing retainer to a different type for later production engines, these can be used for older engines too. David

The picture I posted was from the listing, I will take some of my own when it is here. I was wondering if the engine or starter had been replaced as the military green looks out of place with the rest. And yes it has chain drive to the front wheel, as well as the standard O&R throttle control on one of the handles. I did check though all the other mini-bikes I had pictures of & magazine articles on (see manuals thread for links) and couldn't see anything that matched this either as an original product or build it yourself project. I'll have a look through the "web archive" to see if it had a name, assuming it got saved (no pictures of course). David

.....and don't do any research either. David

Clint bought this one, I wonder if I should move some of the sold O&R items to this section for reference. David

Here is what I said less than 12 months ago (post #2) when someone asked about the value of a Tiny Tiger, along with certain chainsaws they are very common, remember to check recent sold prices/completed listings, but be very careful with "buy-it-now" items as ePay hide the actual lower sold price if "best offer" was used. David

That's utterly stupid, I count at least four commonly missing parts too. If they are making $600+ for a rough one, then I need to get my nice complete spare one sold. But there was two different bidders prepared to pay $600. David

It's not just smaller, the MONO text is rounded to match the starter too, personally I would leave the starter as it is, I prefer to keep original decals that aren't too far gone. David
