Hi, Karl.
Well, it might be, but likely not (see below, where I change my mind
about this.) The AUD9103/04 jets are for a horizontal carb
installation; the AUD9141/42 are for a 20-deg carb inclination. Both
are 0.090-inch. I'm not sure what all differences there might be due
to inclination, but my guess is that the actual length of the jet body
may differ. OTOH, it might just be the length of the little flexible
pipe that reaches over to the float chamber that is different.
I would say that if the length of the jet body (the brass part that is
all one outside diameter) is the same, the 41/42 set should work OK.
Let me know, please. I picked the details from The Burlen Fuel
Systems Bible (Formally _S.U_Reference_Catalogue_). All claims which
are not factual are figments of my inclination. Or my list.
Donald.
