I noticed on JBM's page it says "slide holes on Honda CB 350 and 360 go on the intake side". With the stock diaphragms on my 305 there is only one way for the slides to go in so this is not addressed in the manual, but with the stock rubber gone now there are about numerous ways with these replacement JBMs because they aren't fixed in place. The rubbers can only go one way but the slide can go any way. I'm going to assume I should line up the holes on the bottom of the slide with the intake side as in the Hondas, unless I hear otherwise.
