Well done connersw

its a great feeling when you get these beasties to roar into life,
the sound and a smell that will stay with you and is quite unique
A smear of silicone around the edge of cover, and a smear of grease in the case (stops it sticking) insert screws a few turns, then push the cover home, nip the screws wipe off excess. Also a tiny smear of silicone on the threads will stop the screws leaking or slackening.
