Hi My 68 t120 as developed a habit of cutting to one cylinder then cutting out.. There's plenty of fuel, it starts after its stood for 10 mins... Has any one got an idea of what the problem is? Sticky value? Timing? Jon
If plug is not fouling and color is a darker brown which is good, I would start at the points gaping assuming it has (2), if OK then the coil/coils again assuming there are (2). I need more info of your setup. Tiger or Bonnie duel coils or single w/ duel output, duel points/single or electronic.ignition.
