Please explain fuel plate profiles to me
I have a #6 right now, Its a Stupid looking profile, I know 0 is flat, 10 is half moon, 100 is curve at bottom and straight all the way up. So the arm that rides up these profiles, Does it supply more fuel the closer to the plate it is or what? I guess I dont understand because a #6 shows to make more HP but it dont let the arm come near as close as say a #10 does. So what gives? I have the #6 all the way forward, and also the AFC all the way forward and had to adjust the arm to ride up and not go under. I have a #10 plate and havent installed it because If I read this stuff right the #6 gives more Power Man I just dont understand.

The travel of the governor arm to the front of the pump gauges the fueling. The profile of the plate determines the fueling to the RPM. Further up the plate as RPM increases. The #6 plate, from what I can remember, has alot of upper end fueling (over 1800 RPM) and is made for more automatic transmissions as it fuels at higher RPM and higher line pressures.
The #10 plate has a more aggressive mid range fuel and pulls back at top RPM. The #0 plate is well, full fuel at any time the AFC is at full travel. Having the AFC at full forward doesn't allow for complete fuel plate contact on some pumps due to the geometry of the pump.
Most guys grind a #100 to try and control low RPM fuel and then go to full fuel at mid to upper RPM. I would throw in the #10, it will give you more power that the #6 in RPM's you weren't used to..
