Isn't the purpose of the anti-stall device to keep the engine running upon rapid deceleration? I thought it was simply there to keep some air entering the carbs at a controlled pace somewhat equal to the fuel that is still being sucked into the engine, when stopping quickly. I never have messed with the one on my G coupe other than observe it extending and retracting when "goosing" the engine by hand. I do remember setting it up per the manual, but that was many years ago. Assuming my assumption is true, then sounds like there is a miss adjustment on those cars that are experiencing a surge or something else is amiss which is causing an erratic idle. I'm too lazy to get the service bulletin out and read right now to confirm, but this is my understanding. Basically a passive device until deceleration occurs. My 2.5 cents for a Saturday morning.

The curb idle is adjusted the same way as the F/G however, by turning the bypass air bleed screw on each carb which essentially changes the idle, I believe, by altering the fuel/air mixture. Fast idle is adjusted via a separate screw on each carb and each carb must be adjusted to the same fast idle speed independently. The manual chokes are helpful to start and keep the brute running, but I don?t think they help as an anti-stall. Once the engine warms up, the chokes are off anyway. In very cold weather ? good luck. Best answer is live somewhere warm or simply don?t drive a J/ramK in very cold weather with a cold engine on a major highway, as it it can be tricky keeping it running until the carbs get some heat from the exhaust heat tubes. Probably true with an F/G as well. Once warmed up it should not stall. > > C300Jly, > Carl B > > From: Rich Barber > Sent: Friday, March 08, 2013 10:26 PM > To: 'Bob Jasinski' ; 'Andy Mikonis' > Cc: 'Chrysler 300 List' > Subject: RE: [Chrysler300] anti stall device-F&G, not J&K. > > Whilst on the subject, my brief study of the ?64 parts manual and pictures of J&K ram engines does not show the anti-stall device on the J&K ram engines. Perhaps that is the major difference between the 2903S carbs on the F & G and the 3505S carbs on the J&K (in addition to the change from automatic to manual chokes)? Perhaps Chrysler engineers solved the surging with internal mod?s in the carbs? Or maybe just the conversion to manual chokes?or maybe some slight difference in the linkage and its springs? There?s always a reason for surging and apparently the problem is not universal, even on F?s & G?s. > > However, the proper K ram block in my K parts car came to me with red-painted short rams, 2903S carbs and the anti-surge device. Hopefully, the anti-surge device has its diaphragm intact and not leaking (always a good thing). No telling how that swap came to pass. Each car has and holds its secrets (TBTG). > > I?m still looking for proper 3505S carbs but am going forth with the 2903S?s. They?ve been rebuilt and ready to feed that thirsty 413. I picked up the bucket seats for our K-rag from my upholstery guy today and the new black leather Goers hides look great. I purchased a rather generic foam kit for the front buckets from Legendary Interiors and the foam pieces took some work and trimming to fit. There does not appear to be a foam kit for the rear seats, so my upholstery guy will have to carve the foam for the bolsters from scratch. > > C-300-K?ly, > > Rich Barber > > [Non-text portions of this message have been removed] > > [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylangYahoo!
