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 indicates that the jets are not correctly centred. He proposes taking the carbs off the car and centring them appropriately.

  1.
How important is this "click"? Not centred correctly....does this effect performance? Presumably their falling at different speeds indicates a certain lack of synchronicity between the carbs??
  2.
Am I going to need new jets? Approx £43:00 each. Seems to me that being screwed down into wrong position may have distorted the rubber.....

I could do the work myself but fear that other things are getting in the way right now.
Simon
