The pins get stuck in the posts in the carb body, and a stuck one does not hinder the movement of the float. Perhaps you have never experienced this?
In principle right, but when a pin is stuck - mine never were - it can indicate to an aggressive abuse with pliers. When this happened, the amateur probably didn't know how to handle these delicate parts and then anything is possible. In all my replies over the years, I've stressed it is absolutely essential the float can move as lightly as possible and one should inspect the swivel pin and polish it. Gruzzel's video demonstrates how little it takes to impede the floats movements. Even in a perfect condition - the video shows - the movement is not continuous but happens in increments. That tells you.
The OP's float obliviously needed adjustment, and responded favorably. [...]
Yes, and it is a pound to a penny, someone has been at it before; most probably a reader of this forum.
But... maybe you, Sir, can explain why only
this float needed 'maintenance' and
not the other three.
Maybe you, Sir, can explain why in the other fora this tampering the floattangs, never surfaces as a subject. Here's a hint. In Europe not that many have the Clymer manual.
Maybe you, Sir can explain what I - in over 43 years and 140.000kms
must have done wrong to arrive at
not having to do this 'maintenance' ever.
