DJ4A distributor advance springs

[John Gould]

Thanks folks, I do also have a DJ4 and that's just as Parazone states, but this distributor has DJ4A stamped on its plate followed by the number 7, that's probably the degrees of advance as its baseplate is stamped 7deg. Actually the distributor is in pretty good condition but the auto advance springs have stretched slightly and that, along with a bit of accumulated wear here and there in the weights mechanism, means I'm only getting very slight sprung movement on the cam spindle, certainly nowhere near 7deg. If I can't get new springs I might indeed need to open out the baseplate holes and time it to max advance as suggested in another thread, but I'd really rather keep that as a last resort.
I guess the DJ4A is an interim distributor and if so I'm starting to think a pair of DK4 springs might be just what I need - does anybody know if that is so?
