The needle retaining plate part #7 in the Mikuni tuning / parts on line chart that sits under the spring & on top of the slide has a tab bent down that was in the groove where the cable goes through. It also has a 2nd hole in it that does nothing if assembled as shown in the parts diagram. Is this the correct way it goes? If it's turned over with the tab sticking up, the cable could be put through the 2nd hole and be locked in the correct location in the slide too. This seems more logical to me but I have very little experience with Mikunis so don't know. Also mine has no markings at all except a MIK on the body. It is very old I know but shouldn't it say if it's a 32, 34, 36 etc??? Thanks. Glenn T.S.
