Moving on back to diesels, yet another Russian make
A MARZ 2.5cc rear induction NIB example
The engine comes in a pretty large box (for the size of engine) and the box apart from the engine also contained, a piece of fuel pipe, mounting harware, a 8x4 prop, and a tommy bar to tighten the spinner nut.
There is also a booklet of instructions, of which I can not make head or tail as it is in Russian. Any one knows some to translate??

The first 4 pics show the box and what one finds when the box is opened
   

Some shots of the instruction manual

Now for the engine

Take a close look and you would see how agricultural is the outer casting

looks like water pipe fixtures   

In my humble opinin the water pipe may have a smoother texture

The only gasoline engine I have is SV 17 cc. New but no box or instructions.
I beleive in terms of power it is equal to a 2 stroke 60 glow but the weight of all equipment put together may be equal to a 120 glow.
Take a look

The engine comes installed with plasticky looking standoffs.
Also the prop has two bolts on either side of the shaft, which implies that any prop would have to be drilled.
   

Coming up next  are two 20 size cuties, one from Austria the other from the land of rising sun. One a 2T  the other 4T
Stay tuned...

A rather lengthy but informative article about the Marz diesel can be found here
http://modelenginenews.org/ad/marz.html
The site is also a mine of information on ic engines

The 20 size Austrian beauty. Do I need to say more? NIB, two stroke, HP 20 Gold cup.

I sort of like the polished muffler, and the contrasting thermex coated crankcase.
Have seen and used this engine (not mine) earlier and this engine just rips!!!

Some more

Looks fantastic...

 

The smallest commercially mass produced four stroke by OS Engines of Japan. The OS 20 FS.
My example is NIB.
Would also post the slightly larger version the OS 26 FS sometime later
Till then enjoy the pictures of the 20 FS

The smallest commercially mass produced 4 stroke from the stables of OS Engines of Japan, the very desirable OS 20 FS. NIB
I would also be posting the eleder brother later the OS 26 FS. But till then enjoy the pictures for OS 20 FS

Some more pictures of the engine from various angles

The engine came with a set of tools and a mounting template (why does OS not do that these days??) and a rather comprehensive catalouge of the the then current OS line up

Captain.. what sort of tools ?

sir old engines came with allen keys which were of the sizes of the screws in the engine...!(due the difference in the metric and english measuring systems) like the head screws, backplate screws, etc. they even some times came with the tools for timing the valves, camshaft gears etc.

i think OS even gave mounting screws along with the template. sometime back.!

sir nice to see one of the smallest 4s..!

Time to update the thread.
Here is another engine, a flat twin cylinder glow of 0.30 cubic inches displacement, made in Japan.
The G Mark 30 twin.
Each cylinder is .15 and the exhaust is integral to the engine (can be removed though) with both the cylinders exhausting in the common dustbin style muffler with a single stinger style outlet for exhaust.
The engine back plate has provision for mounting to either firewall or on standoffs
Take a look

And the last three

without a Legendary DA-50 ? one more to the pack (waiting for a tuned pipe)

DA are great engines but not yet legendary. There are others in that category. Maybe after they stop producing the DA's and after a few years/decades have passed they might qualify as legendary.
And BTW I would not put them on balcony wall for the dread of unintentional fall.
Merry Christmas
