Most of you will agree that the original Lucas point driven inductive ignition system is a high maintenance, poor performance nightmare. The later "Lumenition" system (Lucas #41626 distributor), I understand, was not much better because the optical sensing system was unreliable circuit-wise and the LED I.R. emitter and the photodetector are both ultra sensitive to dirt obstructing the optical path.

I have discovered that Lucas has a magnetic pickup electronic distributor (Lucas #41808) and electronic module package used on 1980ish MGAs that is an exact replacement for the above 907 ignition systems. The electronic packages uses the common GM HEI module to drive most any coil. I am using the distributor to drive a MSD capacitor discharge system and stock coil. This distributor is set up for vacuum retard, as is the stock point unit, but unlike the point unit, this distributor is easily converted to vacuum advance by merely inverting the vacuum module and moving the advance plate drive pin to the other hole. A good source for this electronic ignition systems is British Parts and Service, 335 West "A" St., Hayward, CA 94541. Talk to Dorene Carlson at (510) 783-6487. The system, distributor and electronic module, lists for about $200, but with sweet talk she will sell it for about $150.

One more thing... Does your distributor (any and all of the above) leak oil all over the right side of the engine? Replace the distributor shaft oil seal! A superior American made shaft seal for these Lucas distributors is a CR #721513 which can be ordered through any bearing supply house for about $2.
