1980 GS550 Pilot Screw / Washer / O-ring

[Guest]

I'm sure this was a previous owner attempting to rebuild the carbs, but anyone ever seen a mikuni carb with multiple washers & o-rings on a pilot screw?

I pulled out 2 washers and 3 o-rings from one carb??!!

From 5 years ago when I rebuilt another bike, and looking at the guides again, it should only be one washer and o-ring right?

Lord knows all the mishaps that our bikes have been through over the years. Seen some carbs with multiple o-rings and some missing either the o-ring or washer or both. It should be only one o-ring, one washer and then a spring. In that order. The o-ring goes in first. I usually stack all the parts on the adjustment screw first before I insert it into the carb body to screw it in.
