RE: [Chrysler300] Hard Starting 55 C300

["chesnutt@xxxxxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

I would guess the hard starting when warm is a carb problem. The needle and
seat in those years were a steel needle on a brass seat. Carter realized the
problem and started manufacturing replacements with a rubber tip on the
needle. This stopped the leakage and flooding when hot causing the hard
start. This was a problem on our 1957 300C in 1958. 

 

Carter Carburetor Division, sent out Bulletin No.  531 General, Dated March
1960. Subject Rubber Tipped Fuel Inlet Needle and Seat Part 25-392S Used on
Carburetors for Chrysler Corp.

Under development for over two years, this new needle and seat is now being
used in production of AFB Four Bore type carburetors used on Chrysler
Corporation vehicles. Because of its resilient sealing surface the needle
tip will make a tight seal even with fuel contamination by iron oxide and
other tiny dirt particles.

The float settings remains the same as with the conventional steel needle.

 

I should have responded to Narve Nordanger when I read the Winter 2019 Club
News. I have known Narve for many years as he has attended the Portland,
Oregon Swap meet many times and has been to our home and also to the storage
building where we store four Chrysler/Imperials in addition to our 1957 300C
and 1970 Chrysler 300 Convertible at our home.

In this month's 300 Club News, Narve talks about his problems with hot
starting his C300. Do any other C300 owners have similar problems ? I would
think this is caused by a starter needing a rebuild, old wiring creating
resistance, or a carb needing attention. 

 

Any thoughts ?
