The usual horrible winters here and some people maybe suffering from damp problems - just a tip for you - do not soak your ht system (spark plugs,leads etc) with wd40, this is a temporary measure and after time the wd40 breaks down the rubber on spark leads etc.  the remedy is to use duck oil - I am a marine engineer and always fully coat all engines with this stuff and the engines look like new and last ,ive even flipped a few boats and fully submersed engines and they have always come off ok - most off you probably already know this but i thought I would try and help anyway!
