*All* MGB chokes are pull on, spring back. HS4 and early HIF4s do have the
inner
attached to a fixed bracket and the sheath attached to the choke operating
lever, both single-strand and multi-strand, although the fixed mounting point
did move
from being part of the front air-cleaner fixing to what looks like the inlet
manifold,
possibly with the HIF4s. The cable could have changed from being bottom
mounted to top
mounted with the rubber bumpers.
