Anyone know the differences? I’m well aware one is intended for horizontal operation and the other is updraft.
Also, are the b (air-operated enrichment) and d (automatic mixture) options bolt-on modules? I know the main jet needle has a different shape, but can the PSH-5BD be converted to a PSH-5C if, say, you had a spare PS-5C core?
