Ok I have 83 Ranger 2.3L 4cyl 4speed Single barrel Carb. Truck acts like it running out of gas if I go over 45 mph or I need to give a lot gas to get over hill. Its doesn't die right away but lose in power and try to backfire. If I don't slow down and pull over let it run at idle it will die and take about 8 sec to turn back over.
I tested fuel flow and that was fine. I rebuilt the carb with no luck, was hoping some stuff was inside. Fuel filter is new. I took a hot air gun to the thing on the carb to see if it would cause something it didn't. Looks like most of the vacuum line are all good shape.
Well I have run out of things to check. Was hoping someone would know what's up and maybe something I should check.
