Yeah,
My Spit doesn't run well on the choke either. I've always thought that was
because my '79 is a water-choke-to-manual-conversion, and it's impossible
to adjust the fast idle speed properly and still get enrichment.
In the summer, it starts right away on full choke but idles best at about
half choke until it warms up. Soon as I get on the main street I disengage
the choke and it will run fine without it as long as I don't come to a stop
within a mile or two.
In cold weather I have to keep the choke on longer, but I still have it off
within five minutes of cruising (not idling).
Did you know there are two idle screws, one for the choke and one for the
regular idle? I found the Bentley manual only to show the choke idle
stop. If you don't have them both set properly it won't idle that well
with the choke on.
BTW what's a '69 doing with a single ZS? Didn't they come with dual SUs?
