Urban Express Carburetor Question

Hey all,

I've just finished resurrecting my first Express NC50. I think it came out very well. I am working on my first NU50. After thoroughly cleaning the carburetor and studying the service manual, I've come to realize the oil inlet tube is missing. Maybe one of the previous 200 owners was a ham-fisted knucklehead and broke it off. I am going to assume there's no practical way to put a new oil inlet in there. Or is there? Attached is a picture of a different carb with the 90 degree bend oil inlet. (Which is missing on mine.)

So now do I remove the oil pump and run this carb on pre-mix? Assuming I can plug the carb oil inlet for pre-mix duty, or go with a Delorto carb Party from Treats? I'd really like to keep the oil injection if I can but I'm not married to the idea.

Also does running the Delorto carb and matching intake keep the machine in fairly stock performance trim (with which I am OK)...

Thank you all for the benefit of your experience and wisdom.(edited)
