williams cuts out when raining

[degm/williams]

water getting into the plug wells or causing a short in the ignition. Check the rain catcher and dizzy/coil components.

what 1fast6 said, have a look at the leads and dizzy cap. Also check for leaks in the rain catcher. Also have you taken the front strip under the bonnet off. When I had mine off it let rain/water/rubbish all over the engine!?
