Re: [Chrysler300] Modifying 1957 WCFB carburetors

["Ron Waters" <ronbo97@xxxxxxxxxxx>]

Hello Parts Reproduction Committee -

If you guys are looking for a project to underwrite, this may be a good one. 
The infrastructure is already in place, so we don't have to shop for a 
vendor to reproduce the parts. Any thoughts ?

Ron

Subject: [Chrysler300] Modifying 1957 WCFB carburetors


Regarding the modifications outlined in the Factory Service Bulletins, you 
will also note that in addition to drilling some new holes and enlarging 
some passages,  they specify changing to new metering rods in both 
carburetors and different secondary jets in the front carburetor, none of 
which are available any more.  However, since I am planning on having those 
modifications made to the WCFB’s on my 300C, I have searched for quite a 
while and finally found a source for the elusive parts.  John Hardgrove at 
The Carburetor Shop in Eldon, MO  (573-392-7378) will make the new rods for 
you on the original machines purchased from Carter when they went out of 
business in the ‘70’s.  These unique, totally manual machines from the 1940’s 
can hold precision tolerances down to 0.00005”   (five hundred-thousandths 
of an inch – about one hundredth the diameter of a typical human hair!) 
However, that kind of precision machining does not come cheaply:  the rods 
cost $320/set of four  and you must also purchase their WCFB rebuild kit @ 
$154 for two carburetors.  The new secondary jets are a paltry $15/pair. 
So, I’m looking at $489 + $14 shipping just for the parts for the rebuild, 
PLUS  the labor for the restoration itself!  This is likely to be a ~$1100 
job!



The best part about having these new metering rods custom-made is that John 
has all the original Carter part numbers and specs as well as the 
Carter-original tiny brass billets, so he can also make the new metering 
rods in the standard configuration as well as three more stages of “lean” to 
adjust for high-altitude operation.  John Chesnutt wrote on December 15, 
2008 listing the Carter P/N’s for these different metering rods.  I can 
forward that message to any interested member if you are unable to locate it 
yourself.

There was an additional Chrysler Service Bulletin No. 1034-CH issued October 
16, 1957 to correct a misprint  in Service Bulletin No. 1028-CH (August 30, 
1957).  That misprint affected the dimensions of the modification to the 
carburetors; to wit:



Quote:  “Please note on Page 2 of Service Bulletin No. 1028-CH in Figure 1, 
under the drawing of the “Air Horn” the Primary side should be 11/16 inch 
and the Secondary side should be 13/16.”    (The drawing in #1028 had these 
dimensions reversed)

There was a fix issued in July 57 but I thought the 58's would have had that 
already done. I can send you a copy of it this evening.
