If its got no float bowl and with that jet it should be an HIF38
HS4 and HIF38 needles mainly start with A
HIF44 needles mainly start with B

If there is no float bowl on the side, then it's a HiF type, if it has a separate float bowl then it's a HS type
The two main ones are the HiF 38 (with a 90 thou jet) and a HiF 44 ( with a 100 thou jet).
If you measure the diameter of the opening at the engine side where the brass butterfly lives
the the diameter should be either 38 mm (1 1/2" in old money) or 44 mm (1 3/4").
I've seen a B needle in a HiF38 and likewise an A needle can fit in a HiF44--they don't run too well

Which one don't run very well or is it both as i have heard they are better than the HS carb

he means the needles commonly being used in 38's and 44's being used opposite from standard.

Sorry,
What I mean't was when the HiF is set up it works well,
However you can fit a B needle into a HiF 38 carb 90 thou jet, and vice versa, then it runs badly.
The B needles are sized for 100 thou jets and the A needles usually used for 90 thou jets.
