Subject: Problem with Coil ignition conversion
Due to magneto issues I have temporarily set up a coil conversion on the Saloon, using an old defunct Bosch magneto as a distributor. At first it worked well, but suddenly stopped. I've tried everything to get it functioning again. I've changed the coil and condenser and cleaned the points and reset them to about 15thou. In a static test the plugs spark nicely. I have tried flicking the points open with a wire attached between the rotor arm and the distributor block and each plug gives a nice blue spark. When I spin the engine on the starter I get a couple of sparks from nos 2 & 3, nothing from 1&4, and then nothing from any of them. Similarly a working magneto sparks on the bench,but not on the car. I've also swopped the plug leads, to no effect.
I've never experienced this problem with the Tourer - can anyone help with advice?
