Neil,
My 73 with HS4s was plagued with a stiff choke (but an easy heater temp
control, completely the reverse of the V8, incidentally). It seemed to be
getting harder and harder so it was time for a very close look. The first
thing I noticed was that although the sheath was describing a nice smooth
arch and not fouling on anything while the choke was in, whn it was pulled
out it was pressed up against one of the overflow tubes. The second thing I
noticed was that the lever that the sheath connects to was not in the ideal
position. I felt that this 'ideal' postion should be that when the choke
was half open the lever should be at right angles to the inner. On mine the
lever wasn't even at right-angles when the choke was fully open, which meant
that when it was closed the effective length of the lever was much less, and
the effort required to start it moving was much greater.
I re-routed the sheath to run the other side of the overflow pipe, and moved
the lever to my 'ideal' position. While doing so I also ran some oil down
the sheath. It is now very much easier.
