[Chrysler300] Re: The great HEMI should be running

> Open to advice and suggestions on what to do.  Both me and a fellow 
club member Sven experience a problem when running the 300 C in a 
traffic jam.  Cars behave like would be starving for fuel.  If 
running on the freeway again the problem disappears directly and one 
could go on for hours without problems.  Temp meter is not showing 
any extremes when the, as we see it, fuel related problem occurs.  At 
this time of year we haven´t even got summer temperatures over
here 
so it will just go worse.
 
> Sven´s car is running on completely rebuilt all original dual
carb 
set up on the 392 HEMI  but mine is still on the modern Edelbrock all 
alu dual carbs but problem is similar.   Svens car has the glass bowl 
filters in place so we can tell the fuel is there and the pump is Ok, 
but the car still is not working properly.

iron manifold and the carbs from regular re-building kits.  Any 
experience if this is enough or if the old ones (asbestos content?) 
is a must?  How to check if the manifold gets proper cooling?    
Anyone experienced over pressure situation inside the float chamber 
of the carbs that would block the fuel passage due to the complete 
carb is getting too hot?

It might be your fuel.  In the early 80's, Dodge cop cars had same 
problem.  It was found recycling more gas to the tank solved problem, 
using fuel to cool carburetors.  I don't know if your local fuel 
is "winter blended' like U.S., but the problem might go away in a few 
weeks.  New gas is made with many lighter ends now and boiling point 
has been lowered several degrees.  Pollution standards change in warm 
weather and fuel mixes change.  I changed heating in my garage from 
32F to about 40F this winter.  Only effect was 17 gallons of gas 
(filled in October) was gone by April 10 when I awoke the beast. Have 
not moved other car yet to see if cooler side of garage made a 
difference.
