Mine arrived safe and sound , one or two nice rarities……very well done to all involved.

With all due respect , if a company can’t make a relatively straightforward cutting cylinder , something is seriously wrong with them.
It would be a doddle for any reputable engineer.

Like all Hayters they were well built , but painfully underpowered.

Andy.

[andyfrost]

Charlie , it’s a Hayter , but don’t recall the model name , a neighboring grower to my Father had one which we used to borrow , I spent many hours using it.

Andy.

[andyfrost]

Yes you can , I’ve done so many times before.

Andy.

[andyfrost]

It could be coil or condenser or points , what colour spark are you getting?? , if it’s yellowish then a component test is in order, are or were your points badly pitted/burnt
Personally I would bin your so called spark tester , they are the most misleading toy you’re likely to waste money on , especially on Villiers ignitions , which it has to be said are notoriously weak.
Yet again , just try connecting your lead directly to the plug and see what happens , remember all early Villiers HT leads had a simple brass direct connector….for a very good reason.

The 24T2 is a very widely used carb , I don’t have the info at hand , but it is available , it will give you the jet numbers according to varying applications.
One tip is to disregard the main jet and replace it with the variable one , you can then compensate for wear in the butterfly ,(within reasonable limits) which is a common fault. Google up Zenith spares and you should find a host of suppliers of spares.

Andy.

[andyfrost]

In that case discard the plug cap and connect HT lead DIRECTLY to plug.

Andy.

[andyfrost]

What type of connection are you using from HT lead to plug.

Andy.

[andyfrost]

ALWAYS try for a spark DIRECT from the end of the HT lead , if you have a suppressor fitted remove it and check for a spark directly from the end of the lead.

[andyfrost]

From memory all Mk12s had a 14mm plug fitting, along with later Mk10s , early Mk10s had 18mm.

Andy.

[andyfrost]

Plug is Champion j8 (or equivilant) , I usually use Garden Hire Spares , for coils.

Andy.

[andyfrost]

Set points to 020″ , you will need to source a cover , is it two or three screw mounting.

Andy.

[andyfrost]

Have you looked on the points hosing cover , it’s usually given on there.

Andy.

[andyfrost]

The wire you’ve highlighted goes to the points ,(in this instance directly onto the end of the condenser) the other uninsulated wire is Earth. Try wiring it up correctly , make sure your points are clean and set , and see if you have a spark.
A modern replacement magnetron coil should be available , which will eliminate the need for points and condenser.
