It's almost certainly water in the HT leads. If the plug wells are now dry (or dry-ish) then take the plugs out and squirt some WD into the foot of the wells, so that any remaining moisture is blown out (or down into the combustion chamber.. it won't hurt any).
Also make sure that under the HT leads is clean and dry. Don't use WD40 since it can sometimes fail to shift water and just sit on top of it. Use Contact cleaner, since it dissolves water and then rapidly evaporates.
The plugs and leads should be able to go back on without anything else - nothing will have been damaged from a spot of water.
Also check the plugs into the coils and also the upper end of the sparkplug boot (at the coil end) though these are tucked well out of the way and ought to be clean and dry.
It mau be worth getting the beast into the garage and looking at the motor in the dark.. so you can see any arcing etc. if it's visible.
No bullets for Chaingun..
