Judging by the symptoms you describe there is a couple of things you should
check. 1. Be sure the thermostatic coil in the manifold that works the choke is
not coming open too early. These coils are subject to a lot of heat by being
near
the exhaust manifold and they do go bad on occasion. 2. The missing during damp
conditions usually indicates bad plug wires or possibly a small, maybe even
unseen, crack in the distributor cap, or less likely, the coil itself. When you
changed the ignition system, did you change the plug wires? If not, this could
have been the problem all along. Check the distributor cap, inside and out, for
carbon tracks, this will be the path of any voltage leak. Good luck and tell us
what you find!
