[Healeys] BJ8 HD8's

1. Were any of the BJ8 HD8's fitted with the mysterious "throttle adjusting
screws" mentioned in some of the SU (Burlen) tuning instructions? Not to be
confused with the "slow run valve", "fast Idle screw", "jet adjusting screw"
or even the "plate retaining screw".
2.  On BJ8's (multi-carb instructions) when no "throttle adjusting screws" are
fitted, do you adjust the idle with the "slow run valve" as described in the
SU instructions or do you close the "slow run valves" & adjust the idle with
the "fast idle screw"?
3. The SU instructions say that "on non-dustproofed carburetters, identified
by a vent hole in the piston damper top, the oil level should be 1/2" above
the top of the hollow piston rod." It seems to me that any oil above the top
on the hollow piston rod would slowly drain down into the bottom of the piston
& then thru the transfer holes into the carb body. Does anyone actually fill
their "non-dustproofed" carbs this full? How often does the oil level need to
be topped up on these carbs?
Thanks,
Gary Hodson
