Hi Chris, ref CR I’m using a standard 37 head which has been skimmed — I suppose about 10 thou off. So nothing too drastic. As to where it’s set relative to TDC I can’t say. Once an engine is running I play around with small changes until I can get it happy throughout a wide range of revs.
What I don’t know is the extent to which electronic ignition affects things, if at all. It certainly gives me cracking good starting and a relatively vibration free engine.
