They are HD6s, not HS4s.
A good local mechanic pointed out that my three "piston lifting pins" don't=
 drop with a satisfactory click or whatever. He suggested that this indicat=
es that the jets are not correctly centred. He proposes taking the carbs of=
f the car and centring them appropriately.

  1.
How important is this "click"? Not centred correctly....does this effect pe=
rformance? Presumably their falling at different speeds indicates a certain=
 lack of synchronicity between the carbs??
  2.
Am I going to need new jets? Approx =A343:00 each. Seems to me that being s=
crewed down into wrong position may have distorted the rubber.....

I could do the work myself but fear that other things are getting in the wa=
y right now.
