Yes Pat, but when I went back to Deanes build thread I noted that he has a dual fuel setup for pump & race fuels and this 'popping' condition he is trying to solve is apparently in the coast mode right down thru the RPM range. I get the impression that he is asking the motor to perform in 'road' mode while it wants to be a 'race' motor. You wont find any current computer controlled road car that has the ignition permanently locked at 32° and a 'fixed' fuel distribution device that can work to maximum performance under all conditions with both fuels.
Also with 40mm chokes the airflow will fall well short of the heads capabilities on this motor.
