Strictly speaking, that is not correct . An extended nose plug may be either hot or cold as may be a plug where the insulator surrounding the centre electrode is more or less flush with the plug body.
The determining factor that defines whether a plug is hot or cold is the length of the insulator in contact within  the plug body. The more of the space taken up equates to greater ability to loose heat  - a colder running plug; and the bigger the gap  the lesser ability too loose heat - a hotter running plug.
This may explain it better.

Only just read this - Not so sure about "apparently no lapping required" .  I bought a set of Neway seat cutters forty years ago and always lap in after refacing valves and re-cutting seats . Would consider it good workshop practice (as opposed to manufacturers assembly ) .
 
The Black and Decker valve refacer dates back to the days when they made proper tools and incorporates a vernier attachment for grinding valve stems on engines without adjustable tappets.

Hard to grasp the scale.

I like the "over centre" type clamps that Countax and Westwood used to use when they had pillar type batteries. Easy to whip off in an emergency - no tools required.

I've just up sized my e-tank from a 20 litre storage box to a 205 litre drum. My power supply is a 12 volt battery charger that seems to be running it at around 2.5 amps. Does this seem about right? Have found some instructions and a circuit diagram for a dedicated power supply on the net but I'm better with a spanner than a soldering iron!

Easimow - Kent

Not sure of the differences between a B10/1 and B10/2 but this parts diagram of a 1 may help. What model Villiers engine is it - some had Amal carbs

Easimow and easy to fall off and end up in the flower bed!  Nice idea but very unstable.

Thanks - Sounds too good to be true but will be tempted to try in on the next resto project.

Frost sell a patina preserver but if it's your intention to paint the machine at a later date I'd be wary of applying anything that may contaminate the surface.

That's an early Westwood chassis but using a Dynamark deck. The first Westwood tractors were in fact re- badged Dynamarks, then Westwood built their own chassis and finally their own decks ( welded pans rather than pressed).

That's awful. Think that I first heard of poison Ivy in the song about a child at camp the went Hello Mother , Hello Father!
However I didn't know that we had anything similar in the UK
However we do have Giant Hogweed about which there's a lot in the press at present there was quite a plantation of it near here and apparently it affects some people badly and leaves them with photosensitive skin for several years after the initial contact.

Here's a man who has bought, spent a fortune on restoration and enjoyed his collection but is now making them available for others to enjoy - at a price!

I've got a workshop manual . I'll scan and upload it later.
 
On Edit.
Here it is. I've omitted two pages illustrating special tools but can add them if needed.

I notice that some of the correspondence and manuals that I have are dated 1970  so Headexam may be a bit pessimistic in attributing Mag's demise to the 1950s.
