Re: [Chrysler300] Chrysler 300H idle speed





Thanks John, I absolutely understand and agree!
It was precisely that problem which caused me to send it to Philbin for rebuild a couple of years ago. Before the rebuild, when I tried to set to 650, it would take off and go right up to 900 as soon as  got it over 600 or so.

It seems to hunt by several hundred rpm right now. This problem will need to wait a bit as I am also in the throes of replacing the starter and I have to teach a class on Monday. 
I am also suspicious of a continuing vacuum leak also. I resealed base gaskets of both AFB’s (8 separate surfaces) . The only other place I can imagine is the intake manifold to block. I have ordered new base gaskets, but I have been unable to locate an insulator/spacer which goes beneath the carvb, and one of mine is cracked (leaky?) so I need to replace it.
If I removed the intake manifold, I may just go ahead and replace that flaky camshaft I have and install the correct 300 H camshaft I bought from Fern last year. 
Thanks, Mike Moore

Hi , 
It might be starting to advance if idle is too high. Which raises idle some more. The springs and weights take off the rest location at certain engineered rpm, so idle must be chrysler spec . And parts not worn . That spec varies with different engine setups / distributors. If you raise idle , it can get into an erratic unstable area ?

Thanks Gary, as I said in one of my responses, I did have it rebuilt by the Philbin Group and it looked to be a comprehensive job. It makes it hard for me to think it’s a dis problem for that reason, but it is on my list to validate by substituing another distributor. As someone else said, the fact that the RPM “hunts” between 600 and 700 rpm
engine speed makes the distributor suspect.

Thanks, MIke Moore

I highly recommend any old distributor with unknown history, MUST be rebuilt and setup on a dist. machine. I highly recommend the Philbin Group in Portland OR, 1-800-869-7301, talk to Mark. If I remember correctly, The charge for basic rebuild was $75. Also, they can rebuild or replace vacuum advance.  I installed and recommend electronic ignition.
Note: with electronic ignition you must pay special attention to the voltage out put at the resistor. To high and you will fry the electronic component.  I may mention Philbin is fast and courteous. I am sure there are many qualified to do rebuilds. Any of them are UPS away.

Michael,
A "hunting" condition at any idle speed can be caused by a defect in the centrifugal spark advance mechanism in the distributor, usually a weak (stretched)  or broken spring.  Don't overlook that as a possibility after checking more obvious things that are easier to get to.

Yes, it idles especially rough the lower it goes. It also seems to “hunt” between 500 and 600.
I discovered a couple of vacuum leaks yesterday and thought I had fixed them by removing the base gaskets from the carburetors, cleaning them, and forming a very small (cross section-like a pencil lid) of form-a -gasket  on all 8  surface and reassembled them. It’s hard to believe I still have a vacuum leak but certainly possible. There was also an old smog kit tap into the intake manifold I resealed.
Thanks, MIke Moore 300H

Not sure what you mean by 'marginal'. Does the car run rough and act like it's gonna stall ? If so, I would attach a vacuum gauge to the intake and see what's going on. Problem is either a vacuum leak, or something is out of whack in your carbs. It's not Ethanol gas.

What idle speed are the 300H folks setting? Although my manual says 650, it sure is marginal at that speed. 800 feels better, but I don’t understand what causes the difference. Ethanol?

Does anyone have tips on replacing a windshield on a 61 Chrysler. Lots of chrome to remove.
Thanks
