Re: {Chrysler 300} Trouble in F land.



Steve -

A long-time mechanic nearly 50 years ago told me, "About 80% of all carburetion problems are actually IGNITION problems!"   Based on personal experience, I would HIGHLY recommend getting the Pertronix unit and their matching high-output coil, while also cleverly bypassing the "ballast resistor" to get continuous 12V required by the Pertronix module and coil.  The Pertronix module REQUIRES RFI-suppressed ignition wires to avoid back-EMF interference which can destroy the module - that omission contributed greatly to early failures of the module and hence its spotted reputation in early years.  You will probably easily find 8mm suppressed wire sets, but if you are a stickler for originality, you will probably have to make up your own set of 7mm wires (including the coil) from bulk wires and using your original (or new) end connectors.  I got my 7mm black wire-wound RFI-suppressed bulk wires from Kingsbourne Wire Werks and assembled my own wire set.  While I was at it, I installed the latest equivalent NGK  IX Iridium fine-wire spark plugs; just look up the cross-reference chart.  After priming the carburetors with an auxiliary electric pump back at the tank, my 392 Hemi now starts within barely two revolutions of the crank, sometimes less!     And NO MORE of those cursed dual points that are nearly impossible to get synchronized!

Steve –

 

Are you using stock points, or do you have one of those Pertronix setups ? If you are running points, then I’m with J-Y.
