the actual Firecore units are based on same Mallory setup


Nacho, my understanding is that vertical movement of the shaft is one cause of the spark scatter. The other is an issue with the weights being too light resulting in not enough spring tension to keep everything stable through the advance curve.


I have read about the scattering problem due the axial play of the dist shaft. Tried to save the axial play with a leather piece inserted into the driveshaft slot to add some preload. The leather absorbs oil and don't get dried like the rubber garden hose which was another of the solutions posted around the web. Aside the shaft collar of course. Didn't change the scattering.

I thought once the scattering could come from the slott being larger in thickness than the dist shaft flat end which the leather piece inserted into the slot will also help on get it somehow fixed without any angle play
