SF, the consensus seems to be that your cooling is fine? Regardless, I doubt it has to do with engine adjustment. That said, your timing sounds off to me
quote:Adjustment done on fuel and ignition. 2 degrees initial advance running very smooth,800 rpm, starts easy. 38 - 40 total advance. With low inital advance there is moore throttle angle (individual throttle bodies).
2 degrees, I have 16 degrees initial (no vacuum), I think you lose a lot of power and probably some throttle response. No wonder you have to open up throttle a little more. At the other end I end at 32 degrees, simply as a precaution to keep my engine alive.
Your curve could be losing power and risking your engine's life, just my $0.02...
I agree. 14 degrees initial should be the minimum. Total could be higher, 34-35. I am set at 16 initial and 36 total with a vacuum advance.
It is the rate at which you get to full advance now that you will be experimenting with. Depends on the gas.
More iginition advance increases the cylinder pressure. The octane of the gas is what resists igniting without spark. That's the point you are trying to find.
Engine will run cooler with more advance rather that less.
2 degrees is not where you want to wind up with this engine.
You may wind up with a higher idle rpm as a result. Let that go where it wants to be.
