The leaning with thick dashpot oil is probably not too worrying - from
my understanding the dashpot oil prevents piston flutter and prevents it
rising too fast (and leaning out the mixture) the instant you put your
foot on the accelerator - ie. it's just a momentary enrichment.
A heavier dashpot spring would enrichen the mixture, but probably at all
rpm, although I can imagine that it would enrichen more at lower rpm.
I hope that the data exists somewhere - I've seen adverts from the 1950s
for Shorrocks superchargers with Morris Minors in the picture!
Morris regards,
