Paul,
If you used the Grose Jets that came with the rebuild kit, throw them out and
grab your old jet needles. Never seen a set of the new jet needles that set
properly.
Chances are that either they aren't seating properly, or that your floats
aren't adjusted properly.

Subject: [Healeys] Carburettor trouble
I have just rebuilt and refitted the twin H4 SU carbs to my 100/6 but I am
having trouble with (quite a bit of) petrol leaking out of both carburettors.
I am pretty certain that everything has been put back together properly
(being a novice, I followed the SU instructions to the letter).
The leak seems to be in the main part of each carb (ie needle/jet area). I
have checked the valves in the float chamber lids for leaks and checked the
gap for the forked levers, so I am pretty certain that these are ok.
I am wondering whether the problem is the needles. When I ordered the new
ones from Burlen, the specification stated that I needed 'AJ' needles.
However, I noticed when renewing them that the old needles were slightly
longer (about 1/8") and were stamped 'AR'. Would this be the issue?
Any thoughts, as always, greatly appreciated.
Cheers
Paul Leeks
100/6 BN4
