[Healeys] Mystery leak.

[Bob Spidell]

Both carbs have to come off, as they're on studs and the throttle shafts 
are connected (the connector slides out, but only after you have the 
carbs out). Unfortunately, there are no secrets or tricks; but you'll 
want to use a 'stubby' end wrench (or cut a cheap half-inch end wrench 
in half). Last time I removed them from my BJ8, I went in from the front 
under both carbs to get the the lower/forward nut on the rear carb, 
which is the most difficult to reach. I have numerous scars on my hands 
and forearms from this and other mechanical endeavors (and working in an 
almond orchard; sometimes those trees feel like they have millions of 
fish hooks hanging from their branches).

I don't remember which car you have, but since you'll have both carbs on 
the bench it would be a good time to go through them and replace any 
worn parts (diaphragm for HD, packing for others). In fact, your leak 
could be from a split diaphragm it you have HD carbs.
