hello Lewis, Carl and Eric

thank you for your prompt replies!
I would love to photocopy the article in Yowl, Lewis, is it possible that I might borrow it? Obviously I would pay for all postage.

Re Plugs- sorry to be a bit thick, but the driving instructions suggests 3/4″ plugs, presumably that’s reach. If I measure the reach(seat of plug base to plug end, excluding the electrode) on the B5HS it’s around 13mm(1/2″?), but on a B5ES it’s around 19mm(3/4″?) . Which should I use? the motor turns over by hand with the longer plugs, so no contact, but is that ok?

Please help!
