Re: [Chrysler300] 300G Heat Riser parts

I have manufactured rare parts in the past and this could be expansive and expensive. years ago I made the steel sheet metal fenderwell bolt in parts for the missing units in our ram cars. couldn't sell enough to cover the cost of tooling.

    My first ram car the butterflys had burned off years before I owned it. My solution was to pull the choke actuators from their wells and set them dead soft or just closed, it worked very well, in 1970 and at 5400 feet above sea level. might try it until some one can duplicate the heat riser parts.

Yes but choke pull off action is 100 % dependent on heat riser working right , on both sides ,
A characteristic of ram cars to me is the sound of both heat valves rattling at idle when brand new ., I remember 383 plymouth ram in station wagon , 3 speed stick  , really fast  car , ( despite ugly beyond belief) ; sound of that part of it , you could tell ram without opening hood, Also mass state trooper 62 wagons , same thing . How I know that best left to history

He is not talking about choke parts. The heat riser parts are what is in question. In my opinion, it does not matter if they don’t unwind at exactly the same time. It would be impossible anyway, as the manifolds are not the exact same temperature. On the choke issue, if the choke pull-off is doing it’s job, the engine will run smooth while the chokes are moving to fully open.

Thought about electric , parts from edelbrock afb. Last F went manual choke no / minimal heat riser, like J anK . And max wedge .
The problem with factory 60,61 is they can pull off at different times, leaving you half choked . And resulting idle/ stall issues . Water heated plenum is another way too . I think too much heat keeps coming even with thermostatic valve and working
in 60,61 
George used to put restricting  washers in elbows I think he was right  . No valve . Perhaps the point being maybe we can improve rather than replicate a problematic design ? Worth talking about anyway ??

I would love to see the heat riser parts reproduced, I've been doing without for years on my G.  I'm fine when the weather is warm and I'm using the car, but the colder it gets, or when starting after long periods, it takes too long for the chokes to pull off.

Hi everyone this is something I'm also chasing, would there be enough needed to consider reproduction of such by the club? They are nearing the end of their life on some cars and nos has basically run out, where are the votes? I vote yay,

Does anyone have any spare of the following Heat Riser parts they are willing to part with ?

Counter Weight Shield ( The Heat Riser ) P.N. 1944616 , Left Side

Thermostat ( The Main Spring)  P.N. 2128933

STOP   P.N. 683057  Small flat steel piece with a hole and a piece of, what looks like asbestos wrapped around the other end. Acts like a bumper for when the Heat Riser returns to rest against the stop shaft.

BOLT   P.N. 1736012  Bolt to secure the Heat Riser to the main shaft.

Now, if someone happens to have a Repair Kit for the left side  and they are willing to part with it that would be even better. It would include all the parts mentioned above along with a few more.

The P.N. for the LEFT side Heat Riser is 2084795.

Of course NOS would be preferred but good used will do too.
