Hi all, I’ve just done a complete valve train overhaul on my ‘74 ‘S’ fitted with HIF6 carbs (I think) definitely HIF’s. Before the overhaul the engine was running fine but knew the cam was worn. During the overhaul I’ve fitted one of JR Wadhams uprated cams (an extra 25bhp is claimed ) and changed to electronic ignition (Accuspark kit). Now it’s all back and running I’ve got a misfire under acceleration and it feels like a fuel issue. I’ve balanced the carbs with a gauge and so far I’ve richened each carb by about one and a half turns. It has improved things but not cured it. Now, one and a half turns on each carb seems a lot to me. Because of the new cam do I need to look at different carb needles? Any advice welcomed.
