Good Afternoon,
I have a 1972 Tr6 Pi which had been fully restored before I bought it some years ago. I do not use it regularly although I do run the engine. Every time I run the engine there seems to be a misfire which is present through out the rev range. I have replaced the plug leads and plugs plus the distributor cap. I have checked that each plug is sparking as well. None of these checks have improved matters. Does anyone have any similar experiences and can shed light on what I can do in addition to what I have done?
