Just took my Willy 3 to Nicks place.
He carried out a carried out a clean of the injectors ...replaced rotor arm and distibuter cap as well as leads and plugs...WHAT a difference. He did say that my rotor and cap had seen better days...so not sure if its those being replaced or the injector clean...perhaps a combination of all...anyway very pleased with what he did ...
He is also a great guy and and answered all my questions re Williams C
Thinking about cams/cyclinder head job done next.
