Now we are getting some where. This sounds hopeful.
It is fitted as is in pic at moment. There is no hose to the nipple. So, I am just getting constant fuel pressure across it?
The way it is hooked up at moment, lower line comes from WUR. Upper line goes to fuel head.
If I hook it to plenum, on vac it would pull the diaphragm down and allow lower CP - hence allow more fuel on low throttle? (Precisely what my problem is).
On boost would harden CP by pushing up on diaphragm, and lean boost off a bit?
My boost fuel range seemed reasonable. But I am desperately short of fuel pre boost.
I should hook a hose on to the nipple from the plenum - vac/boost signal.
This nipple is adjustable - does this mean I can fiddle the range of boost/vac signal?
"Thank you for your time."
We may be making progess.
