While my Samurai is idling it is missing. It does not idle like it should it and I believe I have traced it down to a source. I adjusted the carb, timing, added a new rotor & cap for the distributor, new plug lines and new plugs gaped at .07~.08, and added a couple of extra grounds to the endgine. Still no improvement, I unplugged all my spark plug wires one at a time while Samurai was running and the only plug that made no difference in performance was #1. So it seems for some reason # 1 cylinder is not firing or not firing well. This explains the poor idling I believe but what is causing it?.. My only conclusion and only thing I have not done yet is replaced the distributor it's self...................................anyone else have any ideas or have ever had this problem?
