Hi all,
I have wondered if those who have changed away from the DK4 and declare a great improvement are just reflecting on what poor shape their distributor was in rather than how good the replacement actually is. I tried a strobe light with what I thought was a decent DK4 and could visibly see the timing scatter of a varying number of degrees at tick over. A NOS Reliant distributor was much better with almost no scatter.
I am curious about folks' experiences with unleaded petrol. The change from original unleaded to E5 seems to have resulted in both my A7 and AH3000 running very hot. E10 doesn't seem to make any difference in this. I've tried adjusting the timing but found both to be insensitive to changes. Previously I used to advance the static timing of the AH3000 until pinking occurred and then retard slightly but I can't get it to pink any more! What are the burning characteristics of the E grade petrols, how do you time in with E5 or E10 - more or less static advance?
Thank you for your advice.
Dave
