RE: {Chrysler 300} troubleshooting advice for my Hurst



Could be junk. Does it still do it when cold?

 

I would just pull the carb off and put it on the bench and open it up and see if anything looks amiss. I would check the accelerator pump seal as well as everything else. If all looks good, then I would put it back on and take the main fuel line off the carb and rig up a can of gas and have someone hold it up high and see if it still does it. If it does not, then you know it is in the line someplace. If it still does it, then I would look to ignition.

Subject: {Chrysler 300} troubleshooting advice for my Hurst

 

Went to a great car show this past weekend but have run into an issue since.

The car ran great at highway speeds and at idle to and from the show, until I pulled into the street I live on when the engine stumbled and died as if it was out of gas.

I cranked the engine and stabbed the gas a couple of times and it started right back up, but was/is running ragged at low rpm/idle.  If you slowly depress the gas pedal, it will stumble and try to stall unless you feather the pedal to get through that point and up into the higher rpm range, and it will then take off just fine and run at speed with no issues.  Once it gets cold, and you tap the pedal to set the automatic choke, it fires right up and runs fine on the fast idle cam of the carb, but then as it warms up and the choke is wide open, I can't get a good low speed idle and it wants to stall under load until I get past about the 1500 rpm mark, then all seems to be well.  Did I suck some crap from my 54 year old gas tank into the idle or low speed circuits of the carb?  Did something change inside the distributor?  Is the fuel pump only doing its job at higher rpm?  I'd prefer a more logical approach to troubleshooting as opposed to shotgunning and throwing parts at the problem (fuel pump, carb rebuild, points, condenser, vacuum advance, etc.)

Any suggestions appreciated.
