The biggest hill we have locally is not that big but I do end up retarding the advance as I get closer to the top which I would guess coincides with the loading of the engine. I have net experienced knocking or detonation so I must be doing something right without really knowing it... Thanks for the lessons.
It sounds like you’re running a little retarded under your “normal” speed. As advancing upon giving it more gas seems to produce more power. The best way to tell where your timing is, would be to ( at any speed),move your timing lever advance and then slowly retard and you’ll feel where the engine starts to loose power. That is the “sweet” spot for that speed.
