Re: Overwhelming Petrol/Exhaust Fumes

BTW: it is really a PITA to install the Bertone rubber boot. Works only when you heat it up in the sun or in hot water. On alfabb, I found an assembly procedure (thanks to Scott!)

Re: Carb trouble

Hello Damien,
modern fuels have approximately 7-10% less caloric value than Super gasoline from 1970.
As Dinoswede said, try one number larger idle jets - and then increase the main jets slightly.
I must check my current values during the weekend…
