As I'm in the middle of gasket making right now - using THIS PRIMITIVE METHOD - it would be a pleasure to make a few for you, of various thickness to try out....
Please PM your address + required inner and outer dia, and I'll send you a couple of cylinder base gaskets......costs nothing...!

A most generous offer. PM sent.

While I'm waiting for Gluehand's gaskets, can anybody identify this?

It looks to be about 1cc. I saw a picture on a website of an engine that looked almost identical apart from the colour and it was labelled as an "Atom", but I can find no other pictures.

Unfortunately the manufacturer failed to fix the prop driver to the shaft in any way, so every time the engine pops the prop slips 1/4 turn.

Afraid I don't know your diesel, but someone is sure to here on this fine forum.

Re. the prop. driver. I notice a washer between it and the front of the crankshaft.
Perhaps if you remove that then the prop. driver may go back a little further to "lock" onto the shaft??????

I don't know what it is either.
I'm pretty sure it must be "oriental", i.e. Russian, Eastern European or Asian.
Could be wrong of course, but only two screws holding the cylinder down is a bit "primitive".

Just like my dear old lightning bolt Taipan 2.5 cc

Maybe a clue....
To me, the toothed "end plate" of the needle valve looks home made...
However, the rest of the NVA looks very "Vella Brothers" (ALAG, FOK etc...)

Here is a "FOK" NVA, for comparison.

According to the Jiri Linka web-page this engine is a Czech Atom 1cc diesel dating from1972.

On further research, according to the book"Czech Model Engines" it is an ATOM-1.
Made by: LMK Hradec Kralove.
Bore:10.5mm.
Stroke:12.5mm
Weight: 80grms.

Brilliant stuff. Thanks Frog 50.

Gossie, unfortunately there is no taper or spline or anything hiding behind that washer.

I'm thinking I could drill a small indentation in the shaft then fit a small grub screw through the side of the prop driver. That should lock it into position.

Sounds fair.

Another suggestion if the parts are super clean make thin washer that is a tight fit over the shaft from a plastic bag push into place using the washer and prop collar then remove, this will stop any adhesive getting into the shaft bearing, use some loctite 480 black max wich is a high strength high temp adhesive to glue the prop collar on .clean up any excess straight away with a cotton bud and acetone, leave overnight then pull out the plastic bag washer. If ever you need to remove it you can use a butane torch . over the years I have done many repairs using this product good to have on hand . but not literally .

Getting back to my Snipe problem - she's all fixed.

Everybody was correct. I had leaks around the needle valve, the cylinder seat and the backplate. It leaked like a sieve in fact.

Gluehand's gasket fixed the cylinder seat, rubber washers around the needle valve and a home make gasket for the backplate fixed the rest.

It really hammers now. I got 300 more rpm than my PAW 1.5 on the same prop.

So we now have to fix the PAW
Seriously, it ain't normal that a PAW 1.49 is giving less power than a good ME Snipe
