Re: Spark advance
Guys, I am finally getting to under stand the spark advance from this thread. I met Chuck one day by chance in Blaine Wa; and discovered we have engines rebuilt by the same fellow.
Long story short, being a newer Model A type at the time and still am, Chuck and I had a quick conversation about spark advance which helped my understanding. However this thread has really brought together my understanding and cleared up some miss-conceptions.
My question is; with being hard of hearing, I have being advancing the spark to the point of engine hesitation then back off a notch or two until no more hesitation.
Is that point of hesitation where the the engine begins to ping, I can't hear it but I feel it. In other words, I am advancing the spark until I get a nice surge of power from the engine and it runs smoother. I notice now that my car is running cooler, thanks to Chucks explanation. I know this because I shoot the Rad and brake drums temperatures after most outings. By virtue of the area I live in (not a big city) the car is my daily driver so am getting used to the vibrations and what little I can hear.
Once again thanks to all who have contributed to the thread a big thank you. The pictures were worth a thousand words.
