Yeah thanks Bill,

I phoned around a little and somebody said to me that "no compression" means more than a little leak - like the valves are all opening at the wrong times. So I agree and don't have a problem with the additional fire. Opened up again and now I'm busying rotating the crankshaft and checking the position of each valve.

Firing order is 1 5 4 8 6 3 7 2 and back to 1. Having a little difficulty sussing out when valves are opening and closing since they're all doing their thing together. I had drawn up a diagram through the 360 cycle (x2) of the crankshaft and now I cannot find the elusive document. Anyway, trundling along some more.
