THERE IS ONLY ONE FIRING ORDER FOR THIS IT HAS BEEN THE SAME SINCE 1960??? 18436572 WITH NO1 IF YOU ARE STANDING STRAIGHT IN FRONT OF THE ENGINE YOUR HEI DIST SHOULD HAVE 2 PRONGS STRAIGHT ACCROSS FACING YOU IF IT IS NOT YOU MUST PULL THE DIST, ROTATE THE ENGINE AROUND TO COMPRESSION STROKE, VERIFY THIS BY THE POINTER ON THE TIMING COVER SET IT TO 0 WITH THE PISTON IN NO1 CYLINDER UP IF NO 1 PISTON IS NOT UP FULLY EXTENDED IN THE SPARK PLUG HOLE YOU ARE NOT AT NO 1 IF THE PISTON IS FULLY EXTENDED AND YOU HEARD A AIR SOUND THEN YOU ARE RIGHT, PLACE THE DIST BACK IN TURN THE ROTOR 1 TO 2 NOTCHES BACK TO THE RIGHT AND HAVE SOME ONE CRANK THE ENGINE IN SPURTS, IT SHOULD DROP IN, THEN REPEAT THE PROCESS TO VERIFY YOU ARE ACTUALLY ON NO1 THEN BEGIN THE WIRING
Most HEI dist are labeled on the coil cover where the module/ power plugs in on the side of the cap It should be the only unused space there , unless you had a factory tach. You will need a plain female spade on you tach input wire and it should plug right in
Yes...timing. Adjust the distributor...back it off a little and set the timing....also check your carb setting for rich/lean mix....air mix will cause this also.
What have you done to the system to cause this or were you trying to adjust something?
It would be great if you could find the Ignition Control Module!!! From my experience on my Jeep...90 YJ 4.2 liter carb. it does not have one...Computer controlled only...
Hey , just take the positive wire from the coil you are removing and feed it to the + terminal on the HEI dist. cap.the other terminal under there is for your tachometer. If you are mounting a master kill switch in the bumper for drag racing- attatch the kill wire to the tach terminal also.
Thats it you just plug the three wire pigtail from the dist. base(pickup) to the cap and you are off.
Remember firing order is 18436572 in a clockwise direction. to find #1 remove #1 plug and have someone"bump" the engine over while holding your finger over the hole-carefull. then line up the slotted mark on the crank pulley with the big notch on the timing indicator. Good luck
