Howdy--first time ask-er, long-time reader.

I've got a 1980 cb750F named Waylon. It's my first bike. (My toyota pickup's named Willie.) I've rebuilt the carbs and turned them out 1 3/4 but she only idles on 3 pistons and lags and jumps when cruising at low speed. When you lay it down she scoots, but I'm pretty sure I still need to synch my carbs.

I've seen the homemade rig with the hoses tacked to a board and know that that's what I wanna do. Problem is, I don't know where to plug them in. There are two male nipples on the carbs which my buddy and I have come to refer to as the "mystery hoses." One has a cap on it and the other has a length of tube which I plugged with a screw. It idles better with the screw.

Sooo...question one--what the hell are these mystery hoses?
          Question two--where to I plug in hoses for synching?

And one more--does anyone know where I can find a list of cone/pod air filters matched with the needles I need for my 1980 cb750F? Not that I feel the need for more umph, necesarilly, but I'm just tired of cussing the carbs back and forth in front of that big, stupid airbox.

many thanks for all yer help!
and happy trails,
paul
