[Healeys] Carburettor trouble

[glemon at neb.rr.com]

Having read the e-mail question "the leek seems to be in the main part of the carb area" doesn't the H4 still have the nasty leaky rubber seals for the sliding jet? If so I would guess this to be your problem, some supply cork seals and some neoprene rubber in the rebuild kits, I have had more luck with the rubber kind, also have had luck polishing the sliding/sealing surface of the jet with some polishing compound prior to assembly.

I have installed grose jets on a number of cars and ran for years with no problems, which is more than I can say for the original equipment float needles, although I understand the newer versions are better, but I have never had a reason to take off the grose jets, and enough bad experiences with OEM style needles to not be inclined to go back.
