Brian diagnosed over the phone quite a strange problem that I was having with an engine that I was working on and supplied a part to resolve it.
(No. 3 was receiving injected fuel, getting air and had two healthy sparks but refused to fire. No's 1, 2 and 4 were all healthy and happy bunnies)
Brian Newby - Beford, normally does my stuff for me.
They are both highly recommended and don't charge silly rates.
