Hi All,
I know it is not an RD part. This one was fitted on a RD400 Carburator as a oil injection hole.
The hole was tapped and this part was screwed in. Now the Original oil nozzle do not fit.
I need to get this same item for the other Carb. Could anyone identify this

I think this might be it. Also please check your PMs. I sent you a message back on the 10th.
looks like a pilot jet out of a cv style carb modified to act as an injector nozzle. kind of clever, actually, as long as the hole was drilled big enough. Tims part he linked is prob the best way to go at this point since the holes are now threaded.
