Lucas DKX2A type AX1 Distributor cap

[garnethb]

I am having difficulty in obtaining a replacement distributor cap for my 1949 Flying Squirrel.
I have tried to contact the Distributor Doctor in Somerset to no avail.
Can anyone assist or point me in the right direction.
Regards

As a stop-gap – to at least keep you on the road – you could use a “four cylinder” cap which is more easily obtainable.

(You could then run a couple of “dummy” plug leads under the engine – that WOULD get every one guessing)!!!

Historical footnote:
It was way back in the early sixties that I obtained from Joseph Lucas in Birmingham a quantity of distributor caps for The club which we sold for £1 each – so starting the spares scheme.

Hello Garnet

Try Stewart Engineering, the Sunbeam S7 / S8 people. The Sunbeams use the DKX2 distributor. Also good for spares for the big generator as most of it is the same. Some differences at the drive end and some of the Sunbeams used 2 brushes instead of 4.

Stan you say that would get every one guesing how about one that uses all 4 leads,mine does as the distributor runs at half engine speed. Eric

Thank you to everyone especially Eric who supplied me with one.
Never did hear from the distributor doctor though which was a bit disappointing.

Not with you on that one Eric!

How do you run the distributor at half engine speed – and where do the “other” two plug leads go??

On a more enlightened note – if you are so inclined, you can very easily fit Luminition electronic ignition to a coil-ignition Scott – the benefit being easy (roadside) convertion back to standards as it retains the points. This eliminates the sloppy points gap which develops in the stndard set-up due to the distributor bearings wearing prematurely running at engine speed.

“Pointless” electronic systems utilise the “Halls Effect” to obtain automatic advance – but it is doubtful if can provide sufficient compass with the distributor running at engine speed.

Stan it runs a austin seven distributor with the 2/1 reduction gear as it was mounted on the end of the dynamo that ran at engine speed so being a four stroke it had to run at half speed. it just means that on the Scott number 1/3 plug lead got to one plug 2/4 go to the other.no problem

I use an Accuspark system on my ’60 Brum with a 2 magnet trigger sitting atop the original points cam. Fires 2 x 6 volt coils at the same time (its converted to 12v). So it has a ‘wasted spark’. It uses the original mechanical advance mechanism of the Lucas distributor. Had to make a new base plate for the pick up coil and a new cap to replace the original distributor cap as it has no ht leads coming from it ( actually it pinched out of the kitchen – tupperware or something similar !). Gives a good healthy spark even at kick start speeds. Never had to mess with it.
