James,
3.5L Buick in MGB
Stock:
Main jets .086
Metering Rod .065
I started with:
Main Jets .080
Metering Rod .062
Too lean
Now:
Main Jets .083
Metering Rod .065 (stock)
Ref #11 in your Edelbrock book.
Power is 2 stages lean
Cruise is 2 stages lean
Happy with this set up.
Robert

It will never run 100% as its a bit big for a 3.5L but rejeting it will
fix this. It easy to do and you will only need to do the primerys to
start with.

PS can not remember jet size sorry.
