Pertronix III & Flame Thrower III Installed

[rindel]

Hi Guys,

I just finished installing the pertronix ignitor III and flame thrower III coil on my 1969 mach 1. Installation was pretty easy. Tuff part was running 12v from my ignition switch to coil, obviously disconnecting the ballast resistor wire through the tach to coil. Tach didn't work right so wasn't that concerned about disconnecting it. One day I'll get it converted. I started with my original coil but the timing was going out of wack.

I ended up ordering and installing the coil afterwards and that made the timing bettter but still not right. With my points, the car ran fine on 7 degrees BTDC. After the intallation the timing went to about 20 degrees. Not sure how that happened but I adjusted it back down. Timing seems to slip every few seconds. I can see it jump with the timing light. I'm not sure what it is. I did notice on the pertronix web site that they recommend stranded plug wires while mine are standard stock ones. I'm not sure if stock wires are solid core or stranded. I can't imagine this being the reason for the eratic timing. Any advice would be appreciated.
