Hi All-
I recently purchased a rebuild kit for a WCFB Carb from a Studebaker parts vendor and commenced teardown. The kit does contain some generic parts for brand x cars as well, mind. My problem relates to the two small needles supplied loose in the bag. These, I believe, are the 'accelerator pump discharge needle' (shown in the Studebaker repair manual for the WCFB, fig 67 part no 5). When I was cleaning the carb I had to resort to blowing compressed air through a number of passages and had to remove four jets to facilitate clearing some stoppages. This thing was pretty fouled up because it had been sunk in a carby cleaner tank years ago and not broken down for repair. The upshot of this is that even though I'd shaken everything out, cleaned and soaked it, the needle down at the bottom of the pump discharge nozzles was still stuck down there and I was unaware of it. After blowing it out for a few tries eventually "something" shot over my shoulder with a pop and I figured it was more than just a mere blockage that shifted.
Yep, sure enough on reassembly, I was up for a new needle to go in there but which one do I use? I don't have an original to look at. Just looking at the two replacements one looks about .015" longer than the other and I inserted it into the chamber. I screwed the discharge nozzle back in place with its gasket and shook the thing so I could hear it still free to rattle down there. I know it isn't bound down there, but does any body know whether I've chosen correctly?
