I have a 91 Ranger with a 5.0 swap. I am very close to getting her moving but not yet. She is running but when I add a load to her, (put her in gear) she seems to not want to run. I was thinking that sense my fuel regulator gauge is not registering any PSI? I looked on the Mallory sight and didn’t seem to find a print out off the instructions that I have seemed to misplay. I would guess that you loosen the top screw for more PSI and turn it clockwise for less PSI. I need 5 to 7 PSI for me carb. Could this be the problem?

Thanks for your help.
