Joe,

 Actually at home we never found rain a problem with the TE 20s as they had tight fitting rubber caps over the ends of the four plug leads and the distributor leads.  I think old Harry had it well fixed in that regard.  I'm in the office now but I think the 201 is the same????

Keep thinking Joe - there's more to come and get that cream job well and truly fixed!  Don't spoli the strawberries for the want of some good cream.  If necessary we'll apply for an import licence for you to get some of our Jersey cream in past your quarantine men!

John
