All my o rings should be new because (allthough its an 81) the engine was recently rebuilt. The 'carburetor assembly' is very clean and looks brand new. The guy i bought it from said essentially the whole bike was new accept for the frame, the tank, and the instrument cluster. might have been bs but nothing on it LOOKS thirty years old. ok so is the new consensus that the drain screws all came out some during the carb assembly removal and just need to be tightened? that seems about as likely as something getting inside all of them and blocking the needles... ill get out a digital camera and get some pics on here. p.s. i feel silly for thinking the drain screws were like an on/off switch. i've been looking at carburetor assembly diagrams for days now and they are clearly screws... sigh, chalk it up to inexperience! haha

Just tighten them up. Caution - nip them up carefully, because it's quite easy to strip the threads in the float bowls. Oh, and whichever forgetful sod forgot to tighten them up probably forgot to tighten the choke cable assembly too. I wonder what else he forgot?

Nice snaps, from the appearance of the screws (no gouging that I can see), it looks like somebody was careful. On the #2 carb, I see a hose is missing from what looks to be an accelerator pump.

Did the 900C have accelerator pump carbs? Paging Mr Olson.
