Can anyone with the electronic ign unit attached to the side of the distributor please let me know what No's are stamped on the distributor next to the module and the year of manufacture if it's original.
The No on the Sisley is SP101C, I tried to replace it with a newer unit with the numbers SP101A. Two things happened, firstly the distributor would not adjust to the 15 deg BTDC as the adjusting holes would not let it rotate far enough, Secondly when I replaced just the module to see what effect it had the engine died as soon as it started to get warm. I let the engine cool and again it started no problem but as soon as it got warm again the engine spluttered to a halt. I then put on the original module and it was no problem at all?
The reason for changing it is there is a very slight hesitation when driving at a constant speed between 20 to 40 mph, when accelerating or at motorway speed or when the engine is at idle there is no problem what so ever. It is as said hardly noticeable but as always I know it's there so want it as perfect as I can make it.
Anyway trying to find out what units were fitted to what year and what differences there are in the unit's?
