Just thought it was worth leaving a mark in the sand on the furum. I have just replaced my Petronix I igniter that came installed with the truck with a new Petronix II igniter module. I have done this as the pertronix I has known issues with burning out if the ignition is left on and I wanted to have a spare unit incase it ever failed.
I had also had problems with the truck breaking down. I traced this to a faulty flame thrower igition coils and if anyone is interrested there is a video of me sectioning the old coil in the build diar section of this forum. Link here: https://youtu.be/cCW_WZbr4ZY
The new Petronix igniter looks to be an identical form factor to the previous version but I decided to replace the rotor arm. The new rotor arm wont seat it hits the top of the igniter. On closer examination of the old rotor arm I see that the skirt had been cut down by tne previous own by 6.5mm.
Anyone had simiar issues ? or any thoughts ?
I will upload a video later to show in more detail perhaps this will help other etc. Video Here: https://youtu.be/DvLZdTNQk2I
My truck is 1953 3600 with the 216 engine and delco distributor. Im actually thinking about just fitting points!
