I think you should give up Ken, put all related material in a box and ship
it to South Carolina for disposal !

Subject: SU jets question
Friends -
I have a '72 MkIV that has twin SU carbs installed,
allegedly from a '70 model. They are impossible to
tune and I'm thinking that the jets are incorrectly
installed.
Fortunately, the DPO left a couple carb rebuild kits
in the trunk - but no indication of which goes on
the front and which goes on the rear. They are just
in boxes that say "Lucas rebuild kit" (yep, Lucas).
Using a pin gauge, I've discovered that the jet hole
(where the needle goes after it's all assembled) is
smaller on one than the other. Does the smaller jet
go on the rear, or the front?
Thanks for any help,
Ken Strayhorn
