Thanks for the background info John. Very interesting. I was initially concerned about reliability with these units because I thought they were a relatively new adoption by engine manufacturers. I think your comments about Champion/Lasar CDI units are about right because Ben McGuiness, another KF7S builder installing the injected version of my engine here in Melbourne told me some time back that he had to swap out his CDI unit for a replacement because of performance or reliability issues. But from my reading, it appears that the CDI systems seem to provide more efficient spark energy - at least that's the claim - which can overcome some common starting and rough running problems, i.e. over priming, fouled plugs etc. Almost sounds too good to be true, but i'll know in around 4-5 months - hopefully.
Yes, Bruce, looking forward to sidling up next to Ross's KF in the new year.
