Subject: Coil ignition
Has anyone experience of using coil ignition on a 2 litre? After endless magneto bothers (despite expensive rebuilds) I've fitted a coil conversion that uses the ubiquitous Bosch 009 distributor. Usual practice with a 2 litre is to start with a little manual retardation then whack it straight up to full advance when it fires. The advance curve of the distributor is such that full advance (set to 36 degrees) is only reached at about 2500 rpm from about 15 degrees advance at idle. I'm concerned that spending more time with less advance may cause an engine that already overheats at the drop of a hat to overheat even more easily.
