Take your HT leads off and your plugs out,... wrap them in kitchen roll and put them in your airing cupboard for a couple of hours,.. this should dry them out well enough to check if they're the problem when they'r re-fitted,.. Make sure all the connections on your dizzy cap and HT lead ends are clean bare metal and not bent or corroded.
Decent HT leads should be ok without the need for sealent,
Rather than try to de-flood the engine,... just dry the Spark Plugs off and clean them with some white spirit, put them back in the engine and try to start it.
Everything needs to be bone dry,.. when the dizzy is all dry and clean wrap a marigold with the finger ends cut off it round the dizzy,.. the HT leads pop out the fingers and wrap 'laccy bands round them to seal them off,... best form of waterproofing until the shops open and you can buy some new items
Hope this helps a bit, Merry christmas.
