Some shop innovations are too obvious. Please tell me somebody has done this before:

I really like remote needles when practical. I have a lot of them laying about because I've converted a lot of OS engines from R/C. Yesterday I was setting up a profile flapped ship grabbed an LA46 to convert over to CL. I was getting ready to swap out the backplate and I had an idea. Installed a venturi and a ST spray bar. Took the needle and used the Dremel to cut off the tapered part. Threaded the remainder into the spray bar about .250, cinched down the collet and then cut off the excess. Connected fuel line from remote NVA to the spray bar. Done.

Anybody else tried this?

Rather than waste a good ST needle valve, just plug that end with epoxy. Make sure you can still get the nut off. Then, if you want to reuse the spray bar, heating lightly with a torch of some kind will burn out the epoxy. ST needles are getting hard to find and expensive! And with epoxy you could use any old OS spray bars or other brands. be sure to allow for spray bar diameter when picking venturi size.
Type at you later,

See if you can find some OS spraybars made for the task, and then you won't have to drill out the crank case.

I've the same thing, but it was with *gasp* Cox product engines.
