89 Mikuni Carb

[gtrosema]

Need help finding an exploded view of carb. O/H kit does not have a very good picture. Seem to have a jet, maybe air jet that is not in the picture. Have done a web search and not had any results that answered my issue. Have the Haynes manual and still not enough info. Have stuck this in every place it will go into but none seem to be the right one. It is not one of the fuel jets in the float bowl. Went to a few salvage yards today in hopes of finding another one to have an example but no luck. Any ideas???
thanks
