I have a 79 Spit too. I had the same problem. I have taken the
automatic
choke apart several times. I think that it may be sticking. I think
that
I will get the manual choke adapter. I tried taking a manual choke off
a 75 spit but there is a flange that was added to the latter models that
make this conversion difficult. Check out a Moss catalog. You will
find
a manual choke conversion kit there. Keep in mind that this is a bit of
a guess.
I hope that someone out there can give me (us) some insight on this
topic.
