Yes, I found that I could loosen the jet tube a bit so as to rotate the fuel inlet nipple to the most convenient placement. That nipple fitting is sort of soft on the surface, has no gasket, seals OK when the tube is tightened up. NV offers a brass fitting also. I suppose it uses gaskets or some such.
I ran the engine yesterday morning after installing the new O-rings. It ran fine once I got the LSN set right.
