Re: [Chrysler300] Road trip UPDATE final

In my experience a bad accelerator pump will impact both cold and hot performance. There could still be a problem there, but I think Tony might have the right diagnosis with suspecting some degree of vapor lock.

On the heat pipes, we had some discussion at Macungie (John Grady, Jean-Yves, Lynn, Jamie et. al.) and the consensus seems to be that with the headers the heat pipes should be blocked but drill a small hole in each block off plate to allow a little heat to help while the engine is cold. When hot, plenty of heat should induct up to the carbs anyway. Having unblocked heat pipes might be adding to the problem perhaps, but Iâ•˙m not sure.

Tanks Charles for the feed backÂ∑

No, I do not have one of those installed, been kind of wondering along those
lines my self as it is a bear to start after sitting for a week or more.

I have to prime the carbs, else risk grinding the starter too long. Last
year ,I had to replace one of the acc pumps that had turned inside-out,
wondering I I may have another problem like that.

Was tempted to pull them out at the meet but thought better of it

Wondering if removal of the inner fender liner cutout would help any?

Did not have this problem last fall during the US Hwy 6 tour, but that was
in Oct and temps were much cooler.

This is the 1st long distance hot weather trip for this engine.

I might add, and some of the members know this, tat I am running 63-64 Ram
headers on this unit with het riser pipes connected and automati chokes.

The heat riser pipes are not blocked

Do you have an electric fuel pump such as the Carter rotary electric pump?
That can make all the difference in the world when it comes to fuel
starvation due to vapor lock. I am a very active member of the Early Ford V8
Club here in Denver and all the cars that are driven on tour have an
electric pump installed otherwise they stand no chance on hot days. I also
have this pump on my C300 and it behaves perfectly on our high altitude 95
degree days.

Good morning USA!!!

First off, Carolyn, Melissa, out probably youngest and newest member BTW,
would like to thank Tony and Crew for wonderfully memorable meet.

Pulled off in 1st lass all around, THANK YOU!!!

Rolled into the house at around 4PM yesterday, 8/6Â∑ Todays history ?? What
is significant about 8/6??

Had rain from Springfield, OH clear thru Indiana

Total miles for the dayÂ∑535 with MPG at 12.72Â∑not bad for a fresh engine
w/2500 miles on it so far??

Now for the discomforting partÂ∑

The F rubs good when cool, like in the morning, 1st off, for about 15-20
minutes.

Then as soon as everything gets up to temp, it will start in with a stumble
when accelerating, kinda like itÂ‚s running out of gas.

Had this problem on the way out alsoÂ∑Â∑

But if I drive like there is an egg under the foot feed, we can get along
just fine.

Thought it was the non-vented gas cap I have on it, so we removed that once
the fuel level got down some, no change.

Stopped for lunch and left the hood up for Â∏ hr, ran great again for a few
miles then same old thing again.

Has got to be under hood heat related to lousy gas.

Was good to get back to IA and a CaseyÂ‚s where most have non-alcohol gas and
the pumps are labeled as such.

Filled up at Davenport, added 8oz of Marvel mystery oil along with the
Â„valve saveÂ‰ stuff I have used for years and took off, no change.

Topped off w/non-alcohol gas at home and parked it.

Going to change the fuel filter and go out this AM while itÂ‚s still cool and
see what happens now that I have a full load of Â„decentÂ‰, albeit low octane
gas and see what happens.

One fellow I met at a fuel stop mentioned I should try a different heat rang
plug.

I am running NKGÂ‚s at present

Other than that, had a good trip home with a side excursion to the flight 93
memorial (still under construction) at Shanksville, PA. Another Â„moist eyeÂ‰
experience as was all of Gettysburg. Both, must see places for any Â„True
AmericanÂ‰
