So I've come in search of which direction to take with my troubleshooting.
Backstory: Ranger with carb'd 351w swapped in using Duraspark ignition from the 84 donor F250. Using the original TFI coil and spliced into the wiring on that to Duraspark harness for my (+) and (TACH) wires. Also add in AutoMeter 5" Tach
Originally truck ran fine. Ran into an issue where it would lose spark and not run unless I unhooked the tach. Figured the problem to be the connection where I spliced the (TACH) wire to the Duraspark, ditched the scotch lock and cut and spliced in. Problem solved.
Current problem seems to be that it seems to "cut out" as I've called it around 4,000 RPM, or sputter and not want to rev past that. Isn't constant, but more common than not. The needle on the tach drops 3-500 RPM with each sputter.
Truck does sit a lot without being run, someone told me "jus' needs a good cleanin' out" but not sure I buy that logic.
Please, before I drop the coin on an HEI replacement, what should i look for next??
