Before I start, I'd like to thank all of you who helped me last time.
Now, my old girl runs beautifully, but she still SUCKS the fuel (66 miles to reserve!

) so, I'm replacing all the stock jets, emulsion tubes and needles.
The problem I'm having is finding the friction fit idle jets. Does anyone know where to get these, or at least have a part # I can work with?
Thanks in advance!
BTW, bike is a 78 CB750a, the jet size is 38.
