Swap fuel plates to help lean out bottom end response?
SO I acquired what appears to be a gov spring from a 180 pump, installed it in my afc tonight, and Whoa yeah!... However I'm still fairly smokey off the bottom. Here's where I'm at:
- "0" plate full forward
- new AFC spring, factory shim underneath. Modified factory diaphragm washers
- foot has been shaved ~.100"
- dialed in the starwheel to allow afc foot to bottom on housing right before coil bind
- pre-boost screw barely touching afc shaft (any tighter and it's going to make the situation worse)
- full travel right at ~42psi
My Issue: the spring is shorter than the stock spring, so it puts the foot farther forward at rest; in an effort to keep maximum fuel delivery I installed the afc housing full forward on the pump. This makes it soggy off the bottom, but like i said, I absolutely love the response once it gets moving.... Could I swap my #0 plate to something like a #6 and lean out the bottom a bit more? Or would that pull more fuel than I think?
