Phil, Why are you saying .046 jets?
97's were used 36-38 on 221's.
I have a couple of original issue 97's; these have '67' cast into them which tells they are original issue on 36 commercial vehicles. These original carbs are also stamped with the main jet size. One has .045, the other .046. So, these are how they came from the factory, jetted to suit 221's. You may want to jet up a bit I think?
