351W 4V ** 4180C carb
Having a problem with the Bronco. When I press the gas pedal, it the carb bogs down. Can’t drive down the road without pumping the pedal to keep moving. It does start and idle okay. Has new cats, dist, rotor, wires, plugs. The carb is a rebuild from RockAuto. I put on a manual choke. Timing set at 10 bdtc. Vacuum at 19 in. New crate engine last year.
I have adjusted the idle mixture screws to 2.5 turns (2front 2back). I would like the grand masters to advice me on the number of turns for both front and back screws.
I will be checking the fuel pressure. I have already replaced fuel filter. I haven’t touched the accelerator pump. This vehicle has no obd connector or any way to get codes.
Any advice appreciated. Thank you.
