Re: [Chrysler300] Chrysler 300H idle speed

Mike -
How are you testing for vacuum leaks ? My method is to hook up a vacuum gauge and get a reading. Then with the gauge still connected, spray carb cleaner at the base of the carb and around the edge of the intake. If the numbers change significantly, you've found the problem.

Thanks Keith for your input. I am not at all convinced I have all the vacuum leaks identified and fixed. I reused  my existing base flanges gaskets with sealant added but ordered a new set of gaskets. I need a new phenolic spacer but have been unable to find one yet on line. I am also concerned that it may be the intake manifold to block leaking. Meanwhile, the starter began to fail so I have to replace it. My plan now is to ship the dis back to Philbin and ask Mark to check it for stability because the timing does move around a bit and I should have realized that would cause the hunting. I need to do that to scratch it off my list if nothing else.  I have also ordered a new set of ignition cables, and I do not think its those either.

If I have to take the intake manifold off, this is probably the time to replace the camshaft with the  stock camshaft (-although as I write that I ask myself “What does that disassembly have to do with replacing the camshaft?”-probably very little as the tasks are pretty much unrelated I think).

I suppose it could always turn out to be a distributor issue, but I'm putting my money on your finding yet one more vacuum leak you haven't plugged. Your symptoms sure sound similar to the challenging ones I had on a Quadrajet GM car until our carb guru Jim McGowan at the Quad Shop found vac leaks in my carburetor. Are you pretty sure everything is tight now in the intake area?

Philbin is terrific to deal with. I am going to do the check idle timing as Marshall suggested and confirm it varies, then call Mark about sending it back for a check .

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.
Happy Sunday,

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.

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?
