I will be going to Newbury but do not plan to have the same stand as Malvern so it is essential that if you require any parts you let me know in advance to ensure I take them with me.

Joe,
The 580 is just an assembly number and I do not believe it applies to the serial number. The 4-37 suggests the crown wheels were produced in April 1937 which seems a long way in advance of the serial number 551 which is 1940. Please see Diesel Daves investigation into serial numbers.

Dave,
From this running gear I feel the machine is more probably 1947

Dave,
1-47 is the month and year of manufacture of the crown wheel.
The gear ratio is 9/34 (9 on pinion and 34 teeth on crown wheel)
The load rollers on a 1937 machine would be galleried (radial slots) but on a 1947 more likely just 3 round holes. Idler wheels also changed from galleried to pressed rims.
If in doubt post a photo.

Dave,
Sorry I do not have an MG2 available to look at or photograph. Hopefully an owner will join in and be able to supply some more specific info.

Dave,
Engine number stamped into the crankcase on the left side. (left as sitting in machine)
Neil

Dave,
There may be some variation depending on year but I believe it will be the right plate (looking at rear of machine) The number would be stamped in the lower left corner.
The second plate mounted lower on the left side carries the patent info for the roadless track.
I have never seen the serial number on the gearbox cover.
Be careful using a powered wire brush, try rubbing chalk or crayon in the area and sometimes a digital photo reviewed with various contrasts etc. can show otherwise invisible results.
Good Luck.

Dave,
Unfortunately the only true id was on the plates and there is no other serial number available on the machine. It may be possible to see a faint indent in the chassis where the plate fits as the serial number was stamped on the plate after it was fitted to the tractor.
If you have the registration number you may be able to retrieve the id from the DVLA and then attach new plates with correct number stamped.
If you need parts contact me njarrett@btinternet.com

The skimmer is owned by Rhys (rocboni)who has been rebuilding it and is trying the water. It is one of two known existing machines both owned by members.

I am not familiar with the 955 but the many versions of the Wico A are clear.
Clockwise or anticlockwise rotation.
Foot or flange mounting (variations depending on engine manufacturer design)
Drive dog / sprocket design again dependent on engine design.
Advance mechanisms for various engine designs.
Single cylinder / 2 cylinder / 4 cylinder uses.
Start multiplying all these variations together and it is easy to see how the 100 plus derivatives can be achieved.
In my opinion I consider the base magneto is a simple and flexible design and have rebuilt many with no real issues and try to keep a good selection of spares.
Cleanliness is the biggest feature when rebuilding as oil / magnetic particles in the wrong place can cause many running issues which do not appear to be logical.

Gareth,
Welcome to the forum and good luck with your search. In the meantime I have manufactured a replacement jet holder for your carburettor and it is ready for you. DC is aware.
