[Healeys] H4 carbs leaking

[ggilliam at usol.com]

Experts...
   I have rebuilt the carbs on my BN4, genuine SU master kit. New shafts, 
butterflys, all the seals and gaskets, etc. The engine starts easy, 
idles down better than ever before, but both carbs leak badly down the 
jet tube. I had hoped the seals would "set in" or something like that 
after some cycles of the choke levers, but no, still a significant 
dripping, directly over the exhaust of course.
   Does anyone have a secret method of installing new seals on the jet 
tubes, lubricants, order of assembly, additional quantities?

  Thanks for all suggestions..
