HOW INCONSIDERATE! It is not all about you, other members that spend the time to share knowledge and try to help won't bother next time. As for me, I will take your advice and ignore your posts from now on. PS: You are way too sensitive for public forums. I read all the responses and could find nothing to be offended about.
Rich, I still don't know why you were offended. All I did was suggest some things to check, and answer your questions. I was waiting for you to read my timing thread, then maybe ask some follow up questions, and then check what we suggested. Instead, you seemed to ignore the suggestions, and then start a new thread.o No: Glad the car is fixed, but do you actually know what was wrong with it?
I think what may be happening is that when you installed the pertronix, perhaps you used the original wire from the ignition that goes to the positive side of the coil. The problem is, that is a resistance wire and the voltage will start out at full voltage, but then it will gradually drop the voltage. Originally, this was to allow a hotter spark for cold starts, but then reducing the voltage as the engine reached operating temperature increased point life. Now that you have the pertronix, that is not needed and the resistance wire may be dropping the voltage too low for the pertronix to operate properly and is causing it to misfire. Try checking the voltage at the positive terminal of the coil cold with a voltmeter and then leave the ignition on for several minutes and check again. If the voltage has dropped below 10 volts or so, you have found the culprit. Either replace the resistance wire with regular wire, or run a new one that operates with the ignition switch. Hope this helps and good luck.
Could be Steve, but the only time the resistance wire is bypassed is when the starter motor is cranking the engine to start. After you release the key to the run position, voltage flows through the resistance wire, so it would drop the voltage regardless of engine temperature. Resistance increases with temperature so possibly it is borderline when cold and then starts to misfire when hot.
