Missing power jet in marvel carb (type b) tsx 388 of my mf135 gas 1965

Hi all, I just dismantled my carb for cleaning since it was leaking when engine off. I noticed that there was no power jet in it. Should i try to find one for it or just leave it as is?
Thanks This is the jet below the nozzle.

Mt TSX 458 for my Ferguson TO-30 did not have a separate main jet. It just used a drilled passage that the needle valve was inserted in.
