[Healeys] HD carbs tuning with modern gas

[goldengt at cal.net]

I have been using the rich needles for years on my BJ8 because the Air 
Fuel meter said I was going too lean up my hills at cruise. I could feel 
it too.
SWMBO is really bugging me about burbling on the overrun.
Today the best I could do for idle mixture was 3 1/4 turns from flush 
instead of 2 1/2. When lifting the little pin, it didn't die but it 
didn't have the momentary speed up either.
Is this it for California fuel or should I try something else?
Forty years ago, I could get the momentary speed up, no sweat.
If I increase timing from about 8 degrees, it will ping.
