Topic: '72 Carb Air Screw

[gatorforge]

I've finally got my '72 rebuilt and running, and am on to adjusting the carbs. I have pods so I will be rejetting, but for the time being, I just want to get it to a functional state. I looked in the manual, and it depicts a very large multi-slotted airscrew. This is of course nowhere to be found on my carb, and in reviewing pictures online (and potentially looking for one for sale) I can find no indication of one of these in the wild. Was there a design change from the manual to the production bikes? Am I missing a part? If I could track one down easily, I would just assume its me, but I cant find hide nor hair of one anywhere. Any help is appreciated. I've included the shot from the manual for reference.

 Can't tell by the picture if that is a first year K0 carb in the picture,looks like one,some old manuals show those. But I believe if you look where the circle is where the number 2 is, that picture of the number '2' is superimposed over what is the air adjustment slotted screw on all 4 carb bodies. Baseline setting for the air screw is one turn out from lightly seated.

The  Honda shop manual depicts carbs for a K0 in the main section.  These have a cable actuator for each carb position.  The later carbs are depicted in the chapter supplements. These have a single throttle cable that controls a bellcrank rod using arm lifters at each carb position.

Which style carb do you have?  And are you looking in the right place for your carbs in the manual?

Cheers,
