… I received some real sound advice on hooking up vacuum advance on my car and making sure to have it hooked to full manifold vacuum so that it increased the timing at idle, and wow, that cheap little $10 part did the trick. I know they make adjustable vacuum advances, but I just ordered a few different standard ones from my local parts store, and found one that activated on very little vacuum at idle and it completely cured my car. I can honestly let my car set and idle on a 90+degree day. Best and cheapest upgrade I’ve ever done to my car!!
Is this a thing? I’ve never heard of this before. …and I assume you mean “advances” the timing at idle…?
So, advanced timing at idle will enable your engine to run cooler?
