I have sourced an e-core from a breakers yard, out of a, Opel/Vauxhall... Delco Remy. This one has the "exposed" (4) terminals. I will fit and surely notice more improved ignition?! The Hei module is being earthed to a designated earth as we speak, also paying attention to the other possible wiring mislocation you mentioned.
Thank you very much for the time you took to read and comment on my post!
