I HAVE A 66 MUSTANG STOCK 6 ENGINE TRYING TO INSTALL PETRONIX 2
CAR RUNS GOOD W/ POINTS BUT STARTS W/ PETRONIX BUT STALLS W/ I PUT IT IN GEAR , AUTO TRANS, HAVE REMOVED RESISTER WIRE FROM UNDER DASH . RAN A NEW WIRE FROM ING. SW. TO COIL ALSO PETRONIX . STILL STALLS, RAN A HOT WIRE FROM BATTERY TO COIL , STILL STALLS, HAVE BEEN FOLLOWING YOUR POSTS & YOU SEEM TO HAVE EXP. W. PETRONIX, SO I THOUGHT YOU COULD HELP. ALSO I SENT IT BACK TO PETRONIX & THEY SAID THERE WAS NOTHING WRONG W/ THEIR UNIT IT MUST BE THE ELECTRICAL IN CAR. ANY ADVISE YOU CAN GIVE ME I WOULD APPRICATE. THANKS MIKE.
 
Did you reset your timing and idle? It's possible that you are idling too low and since pertronix smooth it out, maybe its too low now. Only real thing I can think of. Try reseting the timing and idle. Raise the idle to about 900 RPM (high for now) and try putting it in gear and see if it is still stalling. That will help us narrow it down.

JUST WONDERING IF THE PENTRONIX 1 NEEDS LESS VOLTS THAN PENTRONIX 2. - MIKE
 
first thing to check is the carburetor flooding to cause the stall or do you have a vacuum leak?? if the carburetor checks ok,check the voltage at the primary side of the coil. if you have the pertronix II system make sure you have full battery voltage at the coil. check their website www.pertronix.com for their diagagnosis chart. i sent back their ignitor II because of idle problems. it would idle rough then stall. i even ran a bypass wire from the hot side of the ignition switch to the wire before it went to the coil under the dash, this helped but did not cure the problem. i then reinstalled the original pertronix ignitor & have had no problems since. the bypass is like a heart by pass. pull out the ignition switch,remove the hot wire on run condition,spread the connector & solder a wire in that connector,reinsert connector back into switch connector & tap into wire before wire leading to coil before it goes through firewall.
this worked for me, any questions feel free to e mail me.
one x-factor do you have a radial cam??? if so you may have to drill a .060 to .090 hole in the butteryfly blade between the throttle shaft & the idle port side of the bore. this will allow the throttle blade to close just like a stock camshaft position. this will allow the throttle blade to fully use the transfer slot in the throttle bore at idle & afer light acceration. hope this helps. wsa111
