I bet this question has been ask before but I cant find the answer on the forum.
I have just rebuilt my TEA 20 tractor to an 85 mm bore and I am having trouble getting it to run without a random miss firing of the engine.
Can somebody please tell me what spark plugs I should be using I was told to change from a shot reach plug to a longer reach plug and have been running a set of NGK B4ES. Should I be using a hotter or colder plug. The rest of the electric system has changed new disk leads etc also the Carbie has been rebuilt with new shaft etc.
