The ZS carbs are a known trouble spot for this very reason. The hot water
choke circuits are very weak. Don't know if anyone has done a manual
conversion for this carb, but it needs it. If money is no object, go to
twin SUs or a Weber. The SUs will be manual choke. If you go the
Weber route, be sure it has a manual choke. I put a down-draft Weber
on my 77B and it had the electric choke. Plenty of problems.
