Topic: Overtightened mixture screws... results/fix?

So I'm here at work thinking about carbs a lot on my 75' CB550K1 and while I'm going through all possiblities in my head I recall people warning not to tighten down the idle mixture screws too much.  As I have been careful not to do it but I'm wondering if the PO may have possibly done this and how would I be able to tell?

What would the symptoms be?

Pictures would be awesome.

The problem can be dire on the PD carbs, as the adjustment screws have a very pointed taper.  The 022A carbs that you have are different.  The air screws are hollowed tipped and the taper isn't that shallow.  Still, a gorilla could cause some needle/seat distortion.

The adjust screws restrict the air from the air jet.  Distortions from over tightening could change the air screw setting equality among he 4 carbs.  Meaning: the equivalent flow setting on one carb would be a different number of turn for other carbs.

Why do you think your screws were were over tightened?  Pictures would be awesome.

I don't think that they are but I was curious what the effects and why it was brought up so frequently on these boards.

Monday morning.. bored at work and have been thinking about every to look at when i tear down my carbs again.
