--I haven't done an exact side by side experiment with a stopwatch or timer, but I do have a Hurst with electric choke on an AVS, as well as a G with AFB's and well type original chokes, and my perception is that the electric choke does cool faster than the G chokes sitting in the heat soaked manifold area, since the electric is more exposed to ambient air temps rather than warm/hot air rising out of the cast iron exhaust manifold. I'm sure it varies with the time of year, and whether or not the hoods are opened up as at a cruise night or car show. If hoods were closed, and it was a summer day, the air temp under the insulated fiberglass hood of the Hurst would be a lot closer to the temperature of the residual heat floating up from the cast iron exhaust of the G than at a Spring/Fall or Winter show with hoods up and ambient outdoor air cooling things down.My own behavior dictates that the cars sit much longer at a show than at a cruise-in. The bigger the show, the longer it takes to walk around and see everything. The last cruise I went to on Monday had about 2 dozen cars and it was in the upper 50's with a brisk wind, while two days earlier on Saturday I was at a 600+ car show with temps in the low 80's and not much of a breeze. I was only at the Monday cruise for an hour or so in the Hurst, but fast idle did engage on start up. I was at the big show in the G from 10am until 4 pm, and fast idle also engaged. Go figure.On Wed, Nov 12, 2025 at 8:01 AM henry.schleimer via Chrysler 300 Club International <chrysler-300-club-international@xxxxxxxxxxxxxxxx> wrote:--I have a question about electric chokes that someone with experience may enlighten me.
With a “normal” choke the residual heat from the inlet (or exhaust) manifolds hangs around for quite some time. So, if you stop your car after a run and then start it say ½ hour later, there is enough heat to prevent the choke re-engaging.
However, with an electric choke, I wonder if the choke gets “cold” quickly and could re-engage when the otherwise warm engine gets restarted. I have no experience with electric chokes so I would like to know if this is an issue.
I know with my hemi6 Val, once I start it for the day, the fast idle doesn’t kick in again regardless of the number of stops I do. I’d hate to think an electric choke would engage again and again.
Anyway, I’m not planning to change mine as it works a treat. People can let me know directly with their experiences.
Cheers

Subject: {Chrysler 300} Electric chokes on 2903S carbs?
Had anyone installed electric chokes on the ram induction 2903S carburetors?
A friend has two 1960 ram cars and he's convinced he needs electric chokes.
Didn't find anything in the tech archives.
