With more people going to six cylinder Mustangs, even the first generation, I thought an article on the 200 six load-o-matic system could help. My 65 Mustang has that combo OEM, but I changed it. One must use the proper 1100 carb with the correct distributor or it will not operate properly. Basically the L-O-M carb has a spark valve that determines the amount of advance sent to the L-O-M distributor. It is "sluggish" at best. I installed a 1967 dual-advance (swing weights & vacuum)distributor and plugged the spark advance on the carb. For my engine the static timing is set at 10 degrees BTDC and the weights under the points plate are set to the 10L position. That gives 20 degrees at the crank for a total of 30 degrees. With todays gas I suggest staying below 38 degrees total. I went to 42(swing weights in the 15L position)and it ran great (12 initial + 30 mech.= 42)...until I got some 86 octane gas...probably very old and the 86 being optimistic!  Now I have a broken #6 compression ring and blow-by! Hello .040" overbore! One can play with basic timing but play it safe. Use manifold vacuum with the dual-adv. dist. but set timing with it pinched off. Idle will speed up when vacuum is applied so use the idle adjust screw to get it back to 600/650 RPM with auto transmission. I spent 40 years building street rods, am an ASE engine mechanic and was shop superintendent for a city before retiring. I use BWD SELECT parts, an ACCEL 42,000 volt coil, set dwell @ 38 degrees, gap double platinum plugs at .038", use ACCEL 7mm solid copper wires and use 87 or better octane gas. It works for me...OKAY, there was that little mishap with #6 cylinder. Nobody's perfect!
