Wow

, so it starts at £95, then a £70 surcharge plus £33 vat so ends up at £198.00

Wonder what the surcharge is for.
Would rather buy the AccuSpark for, what was it £40? then take a trip down and pay Mintex to fit it 
Haha, i should start a service

. I got hold of another dizzy and fitted the accuspark to that one and also left in the original wires so i could change back to the old points/condenser one within minutes if ever needed.
