My newly-restored '80 Euro-spec R100RS has an issue with the right-hand carb. The idle mixture screw has no effect. In the past when I've seen this, it's always been the o-ring messed up and a replacement fixed it, but not so with this one.
Bike was a non-running crusted barn find 3 years ago, now everything is new or rebuilt. I did the carbs, and have done about 6 pairs previously, so I am confident in my abilities but ready to admit I might have made a mistake somewhere.
Before I remove the carb and tear it down for inspection, do you all have any suggestions on what might cause the idle mixture screw to not have any effect?
The bike runs great btw, so whatever "default" state the mixture is in apparently works, but I have no ability to adjust the idle mix on that side for fine tuning.
Vacuum screws and rubber washers are new and tight.
Starter fluid sprayed around do not cause any effect.
Enrichener cable is correctly adjusted.
Throttle cable is firmly in the ferrule.
Thanks in advance,
