Worth spending the bob or two then!    I gather modern petrol is of a different viscosity.    I have enlarged the "slow running" jets and improved pick up and have often wondered about the mains...

Much higher rpm "after". Could it not achieve 6400rpm before?

Dd you retain the standard 180 air correctors?  I presume the power figures are at the wheels.

I was thinking Lancias book figure of 90hp may be optimistic, what timing max advance did you settle on?

Excellent, thats about what I am using, but with 125 main 165 air.
