Hi Venn
Mike’s comments about the float chamber draining are pertinent. So do check the seals on the jet and float chamber. Choke control on an H and HS SU has two components, lowering the jet allowing more fuel past the needle …and opening the butterfly slightly. The throttle component adjustment needs to be set up carefully and once working you shouldn’t need to use the hand control at all.
Good luck
Cheers
