Tas tanaka

[pappawinner 1]

Hi guys, I am a new one in this forum.

 

I was looking for info on this engine, and stumbled upon this topic on myoldmachine!

 

I think this is a 22cc P7 engine.
I even have the box of this machine still, and because of this I know it was the engine drill.

My late father bought this engine at a dump store and took a lot of stuff off it. Everything het took off isn't here anymore...
His intention was, that this 22 cc would be used for a big RC model aeroplane. In hose days there were no model engines of this size available.

He made an adapter to fit a glow plug in the cylinder head, thats maybe why there is no ignition on it.

Unfortunately, between the 60's and today, a lot has happened to the storage of the engine.
The carburettor and ignition have been lost over the years.
Everything I do have, and that is what you see on the pics, is in pretty good shape.
I'm a model airplane builder myself and it seems fantastic to me to get this P7 working for a big scale model.

The quality of the heavy crankshaft with counterweight (read; very good flywheel effect) and the construction of the crankcase, cylinder head etc, is in my opinion great!

I see in this topic several pictures where I see the carburettor on it which was originally on it.

Are there any people that can help me finding such a carb, and possibly the parts that are needed to make the ignition complete?

Maybe it would be better if I put a CDI ignition on it for reliability, but that of course would detract from the originality...

Thank you very much for your efforts in responding!

Hi papawinner, your engine looks to be the earlier type, if you look at your top photo look at the lower right side crankcase screw and there is a small v cast recess in the crankcase near Thea screw which is the same as my earlier engines, also I have noticed the two screws that hold the carb manifold are the smaller type as with the early engines I have, so I suggest you have an early type engine? Same as the the one on the right in my pic. I think your engine would have had a diaphragm carb and would have been a P72? Parts are very hard to come by. Good luck with your project. I am in Australia and do have some spare engines that I would sell, but postage overseas is expensive. Cheers Tom

Tom, great that you respond so quickly, i can see the difference between the former model and the other. It does sound logical that it would have had a diaphragm carb instead of a float carb.

I have a vacuum Walbro WYJ type with barrel throttle lying around that might fit. I see that I do miss the intake manifold which is attached to the membrane intake assembly.

But I am still very curious about the original diaphragm carb...

 

and oh yes Tom, my first name is Winfried

Partner doing a shed clean out, has had the  P-7 TAS Tanaka 2-stroke drill in the shed for years, all original and still starts up, he's wanting to sell but unsure of reasonable price to put for it.

Have been researching and discovered theyre rare these days yet still people wanting them whether for parts or to clean up and use.

That’s an awesome drill, even though it needs a little TLC. There’s just something about gas powered drills that I love. Hope you can snag it for a good price.

I was hoping to find out how much would be a good price to sell it for, I dont want to over price it

Just realized I never added any photos on here of the TAS pump I picked up awhile back.

Nice find Paul. For some reason that spark-plug cap reminds me of those used on old CRT TV's for the high voltage connection.

 

@CNew needs to do some more homework , the letters forming part of the model number on these TAS/Tanaka engines gives the tool they were used on, e.g;

*BC= brush cutter

*CS= chain saw

*ED= engine drill

*EG= electric generator

*HT= hedge trimmer

*OB= outboard

 

The history page at "Hitachi/Metabo" indicates the T-23 engine was produced from 1975.

They are also still incorrectly claiming to have introduced the world smallest industrial two-stroke engine (P7) in 1962, how wrong they are.

And they still can't spell Villiers.

Hi David, I have been trying to decode the Tas Motor engine story too! From my understanding the Tas small engines started with the Tas P5 a 20cc engine in 1960. these were available in 4 different types P5= standard float carby, P52= all position diagram carb, P53 single reduction gearbox with std or diagram carb, and P54 double reduction gearbox with either carb.

it seems the Ohlsson Rice 20.6ccwas introduced in 1961 and seems like Tas went one up, In 1962 the P7 22 cc engine was introduced. With a 30x30 bore and stroke, Then in 1964 Tas released all the P7 powered machines, note how the first letter is P designating P7 engine type, the PEG-100 110 volt and the PEG-200 240 volt generators, the PED-3 Engine Drill, the PCS-3 chainsaw sold in Australia under the Mobilco importers name, along with others, including a lawn mower and shearing machine and pump etc.

I have noticed three different variants of the P7 engine first has O/R type pull start knob and start cord roller guides and the fan cover screws on from the back, also smaller screws on the carb manifold. Then the middle variant P7 arrived Circa 1966/7 it has a T pull start handle and different start cord guide that screws on and the fan cover screws on from the front, larger screws in the inlet manifold, and different balance factor on the crank. The third variation P7 circa 1970 has a removable pull start mech. which is screwed on the fan cover. My guess is for easier servicing. I have noticed P7 engines in a few different colours, first is a red colour, then a blue, also silver grey on my generator. And have seen a green one on a chain saw.

in 1973 a new engine family was introduced the QS-22 22 cc without reed valve the engines i have seen are orange, and Gold. The orange ones have been used on the QEG-300 generator and other contraptions, then in 1975 the T-23 family engines were released. The two TED T-23 Engine drills I have are blue. David I would be interested in what you think on my decode thanks Mate cheers Tom
