The simple answer is to get a sniffer and see what the A/F ratio is coming out of the ass end. We used to take the old 300K (blue) up to South lake Tahoe when I was in my 20’s and cold in the morning it would not run at all. Too rich. Friends told me to take along some two step leaner (thicker) step up rods and change them when I got up there. It was like night and day. Ran fine in the mountains and around the lake. When we headed back
down the mountain on I-50 we would stop at Sam’s Town and switch them back to the richer seal level rods. That is why for this new 300K as a daily driver and cross-country mount, I am going to put a throttle body EFI on it. When I did the exhaust last year I had them put in two O2 bugs in so they are ready and
waiting for sensors. James From: chrysler-300-club-international@xxxxxxxxxxxxxxxx <chrysler-300-club-international@xxxxxxxxxxxxxxxx>
On Behalf Of RICK AND DEBBIE CLAPHAM To compensate for altitude at 5280 plus. It was common practice to advance base timing 3° crankshaft. Leaned out carbs main primary metering. Seldom changing secondary jets unless you planned to mountain travel. But with fuels today. I
wouldn't even know where to start. Sent from my Verizon, Samsung Galaxy smartphone From:

on behalf of John Nowosacki <jsnowosacki@xxxxxxxxx> Could be 300 related as well as general knowledge- If one were relocating an antique car like a letter series 300 from mile high Denver (car bought new there and lived its entire life at over 5000 feet) to a new location near sea level, what might one be expected
to have to do regarding carb adjustments or even re-jetting to compensate for sea level operation? Car is running fine as far as starting, idling, and accelerating, but the symptom in question is riding with the windows down and smelling an almost raw gas
vapor odor. No stains on carb or intake, no visible leaks anywhere. New fuel lines, pump, filter, hoses, gasket on sending unit, etc. No noticeable smell when sitting at idle in the driveway, or when operating at speed with windows closed and vent or A/C
on. The smell is less like exhaust fumes and more like raw gas, but no evidence of any gas dripping anywhere. Tailpipes not blackened, no stuck choke or anything like that. Any suggestions appreciated. I've never had this experience on my G convertible,
but I do have a bit of this phenomenon on my Hurst, I just don't know what else to suggest except maybe car is running rich in primary circuits and unburned gases from tailpipes are 'wrapping around' towards the open windows once the car is moving 40 or so
