[Mg-mmm] Identify Dizzy please

[Terry Sanders]

Go to www.nammmr.com and look under "Technical" , "part numbers" for the N
types, DQH6A is what was with my NA and I believe it to be original.  I also
have a 6 cylinder dizzy here that is listed in the book to be for Jag
SS100...it will also work in the N type. I'm not at home right now so cannot
give you the number off of it.

Don,
That is a very good find, The distributor in NA-0686 is also 408684 ,
DUH6A-0, FA 32, 544,  12 degrees.  So you have a 6 cylinder MMM distributor
that rotates CW when viewed from above. My Lucas book does not show this
number.

BTW, most  DUH6A distributors, including 408684,  take the Lucas point set
400415. I am fortunate to have several spare sets.

Also, if stuck with a ACW rotor, the brass pointer can be removed, flipped
over, and re-glued and presto, a CW rotor. The rotor in NA-0686 has had this
modification as the pointer is loose and the directional arrow is underneath
as installed.

New question, I have a Lucas Model DKHA6A-0 , #406358 , type A132 six
cylinder distributor.  Any idea if this will suit an MMM car? Rotation?
Degrees advance??
My Lucas book has 1939 to about 1953 information and does not show this
distributor

Best regards and thanks,

Don,

It is almost certainly a DUH6A, not a DUHGA which I have never heard of
(408683 is a DUH6A).

Many DUH6s will fit MMM sixes provided the dizzy turns the less common way,
ie if they turn CW looking down at the cap ("ACW" according to the original
Lucas catalogues - Lucas always looked at the driven end).

As far as I know no DUH6 can have a vacuum unit.

Check the rotation carefully - you may have a find !
