Haven't had this exact problem myself, but I'd:
- keep up with the penetrant
- mildly (NOTE: MILDLY) heat/warm the aluminum around the locking nuts, which
are either steel or brass (either way the coefficient of expansion of the Al
body is greater than the nuts). Heating and cooling should abet the penetrant
to, well, penetrate
- build your jig or find somebody with a bigger vise--you have to have the carb
bodies secured solidly
- if you can get a decent-fitting socket, if they don't break loose with a
ratchet, consider using an impact wrench. I have a 3/8" impact that will do
30ft-lbs at most, and I've found that--used carefully--it's pretty good at
breaking stuck bolts or nuts loose (did I mention you have to have the carb
bodies secured properly?). This may be preferable to putting a breaker bar on
the socket and twisting the hell out of the nuts (crank the air pressure down
to start, then increase as necessary)
Good luck.

Subject: [Healeys] Jet Locking Nut
All,
I've got a pair of HS6s mostly disassembled but cannot budge the jet locking
nut on either carb. I am presently soaking the jet bearing/jet locking nut in
PB Blaster to see (hope) that it helps. I'm afraid to put too much torque on
the nut until I get hold of a whitworth (I believe 3/8 W) socket. Even then,
I'll have to devise some sort of jig to hold the carb since my bench vise is
1/2" too small.
Anyone encounter this before? Suggestions?
On another note - I've gotten a lot out of this list and finally got guilted
into sending some money to Mark via paypal.
