There are none on the 2317S's on our '55 C300. Special, small OD, flat washers would be a nice add. I think machine-grade flat washers have the smaller ID than the standard stovebolt washers. Lockwashers could be expected to gouge the carb mounting flats even worse. I understand your not wanting to damage those beautiful 2903's. BTW, is there any knowledge of the 2318S carb that the AMA specs for the C300 call for as the front carb?

Got to thinking, are there supposed to be flat washers under the nuts that bolt them to the manifolds?? Seems to me there should be to keep the nuts from gouging the carb flanges.
