Is there a tried and true rule as to where the prop should be as the magnets align with the coil? trying to smooth things out on my toro 25cc ... my motor is shaking at some troubling harmonics.....it is currently mounted directly to the firewall..

I might have to try a soft type mount..

the prop is well balanced but I wondered if I could locate it at a better angle. I only start with electric starter so hand flipping is not an issue for me.

thanks for any help!
