What plug gaps on Ledberg ignition set up smaller lower plugs..?

Hi! gang,

I have purchased G-NIPS and look forward to flying it more down in Cornwall.

Like to get in contact with David Shrimpton as I think he is the closest with a nipper, be good to fly up and see David and Margret.

I've only done the ferry flight, so more to come later.

All the best,

Lloyd

New to Nippering. To keep oil pressure when doing basic aero's what is the
clunk system or full inverted system? What do they cost and where are these items from?
