I have 420 B&M blowers, with a pair of 850 marine holley 80443 carbs on top, sideways mount. The carbs are currently setup with progressive linkage. Was considering going to 1:1 linkage.
Right now they have 84P with a 8.5PV, and 92 secondary, No PV. This is a twin engine 38 Fountain. Pretty much spends most of its time, cruising around 3500RPM, which i believe is right before the secondarys start to open. Would there be any pro's of switching to 1:1 linkage on this setup?
