Thank you Ronnie for this very valuable information. I will go this way. I learned a lot about supercharging and the adjustment of Hillborn injection and ignition on Max Lambky´s Vincent streamliner which I drove for 10 years. Of course this was a bit more power orientated as we were running alky and had 45 degr fixed ignition for the most power.
On my Tudor I have a Chevy distributor that has various screwthreads in the flyweight stop so I could adjust full advance there and still get 10 degr initial timing. I will get back to you when the blower is here - Thanks again for so much valuable input!
