Why would I want one of them Japanese pretend classics when I have a fully working [well sort of] v8 Beast?!
It would appear that the distributor was 180 degrees out. And with the assistance of Simon and Ed's timing strobe, the Beast spluttered into life and is now running the best it ever has in the last 3 years. Much also say thanks to a chap named John in Aberdeen with whom I have been conversing via email and a v8 forum.
That distributor is the dogs! We timed it to about 8 dibbles past TDC. Although it is now driveable, it "front fires" from I presume the carbs/filters as opposed to backfiring from the tailpipe. I have taken it to work for the last 2 days and can (sometimes) floor it without any frontfires and now get the great v8 roar.
I have since spoken to John again, who has set his distributor at 10 dibbles before TDC. He reckons that the frontfiring is because the timing is not quite right, and suggests I try it at 10 dibbles.
The overheating thing has still not gone away though. Could it be the timing? The gauge?
