My 318 dyno results
I changed my initial timing to 16 degrees, total timing 34 degrees at around 3300RPM (still also have the vacuum advance hooked up). You guys are right, it seems stronger. When I now blip the throttle while in gear, it doesn't drop as low on RPM as it used to. I will do more testing later.
I still have my cold weather/engine hesitations though. I believe there actually is a sealed off adjustment screw for limiting the travel of the pull-off piston, I will have to take a closer look.
