The m going to guess that the fuel feed in the top air horn has been drilled larger by the pen markings?

This thought has also crossed my mind as to when that fuel feed may become a restriction. Even though the needle and seats are smaller.

I used the Edelbrock larger fuel fitting p/n 8090 along with a 3/8" barb adapter, but did not drill the feed in the top.

I had the .110" needle and seats
