Hi Brian – I had similar problems on my 55 Desoto and 58 Plymouth. On my Desoto, it wouldn’t go above 45 mph. As it turned out, the chain and gears were well worn. Replacing both and problem solved. So the question for you is, when you had your engine rebuilt, are you sure that brand new chain and gears were used. On my Plymouth, the car seemed to have trouble going over 70. I sensed that it may be distributor-related. My friend with a vintage distributor machine rebuilt it for me. From what I remember, he said that the mechanical advance was gummed up and wasn’t advancing properly. So my question is, has your distributor been looked at by someone with a Sun or other distributor machine to assure that it is functioning correctly ? BTW, now my Plymouth effortlessly accelerates past 70 with no problems. Ron From: BRIAN WALKER Hi Ron, Feels like it is holding back and has a slight sputtering sound. That said, it has never stalled. The motor was rebuilt back around 2014-15. Thanks, Brian From: chrysler-300-club-international@xxxxxxxxxxxxxxxx <chrysler-300-club-international@xxxxxxxxxxxxxxxx> On Behalf Of Ron Waters Brian – Does it feel like it’s holding back, or are you stepping on the accelerator, but nothing is happening ? Has it ever stalled at high speed ? How many miles on the engine and is it original or has it been rebuilt ? Ron From: chrysler-300-club-international@xxxxxxxxxxxxxxxx On Behalf Of bwalk05 Hello Everyone, Anyone have any suggestions for troubleshooting Carter adjustments (or otherwise) for a car that stumbles beyond 60 mph. It starts up fine, idles smooth, accelerates strong up to 60 mph and then stumbles...even at fully open throttle. I suspect there is an accelerator pump issue or secondary is not opening under vacuum. Any thoughts/suggestions would be greatly appreciated!
