your editing skills are as good as your ability to offer information CC, nothing changes. are any other than the 2 dozen OSSers allowed to come here for information (the .info sort of gives a clue)? delete my account please CC, you'll be getting real good at that.

page 50 shows a spray procedure that looks like that little jet in a brass tube, is that it?

this might help B2 http://www.mtsac.edu/~cliff/storage/gs/Mikuni_BS-CV_Carburetor_Rebuild_Tutorial.pdf

from what i can glean from the interweb, the "jet" they show in pic 2 is a press fit rather than a screw fit but can't be absolutely sure. Your assumption it's a left over from a previous rebuild seems a good shout. Sure someone who's worked on these will be able to sort it for you.

any joy from my last post B2?

if you're talking about the tiny brass bit is it this? second pic in the thread. http://www.say what now!?.com/forums/showthread.php?t=159718&page=2

it's the float bowl valve.

item 18. it might not be your exact carb but that's the bit you're looking at. http://www.thumpertalk.com/topic/1060493-mikuni-bsr-float-valve-trouble/

isn't that a float bowl sealing wotsit? when the float rises the rubber bit jams in the fuel feed spigot stopping any more fuel. or not.

I think all Suzuki 100s are twin shock. i'll get my coat.
