The .035 IFR sounds big, but without knowing the IAB it’s hard to say.
Also, if the IFR’s are located at the top of the metering block, you can lower them, and you probably should. Virtually every carb I’ve done wanted them lowered, except two, and one was mine.
I can’t explain why mine doesn’t like the IFR lowered, but you just have to give the thing what it wants.
