Distributor Advance Springs

[Graham Barker]

I have settled in my mind the correct spring selection.  I asked the Distributor Doctor to send me the correct springs for my model of distributor (Lucas DK4A 404440).  Two identical springs arrived in a Lucas packet with 404440 marked on the packet.  So that would indicate that use of a light spring and a heavy spring was not correct for my distributor.  I have fitted these new springs.  They pull the weights completely back together when at rest (this was a problem with the previous springs). Have done some trial running to set optimum timing and the car pulls better than ever.
I hope this is helpful to others who have some doubts about distributor spring selection.
