So I decided to change my secondary rods from DA to the AX rods I had from the carb that used to be on the car. Just wanted it a tiny bit fatter, no other real issue with the carb.
Anyways, I noticed a little slit cut out on the AX rod right at the fat end by the seat area. All I could figure was that this was for a little extra fuel during the transition. These are a factory rod AFAIK.
Anyone else seen that before?
