pilot screw advice

<< < (2/2)

K2-K6:
Crossed over with Ash there.

It's a generalisation,  but CV carbs usually fall into fuel metering of Idle screws,  with non CV types being air metering screws.  Hence the switch.

I always assumed that if the screw was on the filter side of the slide then you screwed in to richen and out to make leaner.
However seem to remember reading on here or somewhere else that the opposite is true if these types of screw (1st picture in op) are fitted..ie with holes in....Did I dream this.????

MarkCR750:
You could be confusing this with info for PD carbs, these have a “fuel screw” , it’s on the engine side of the slide, unscrew give more fuel, screw in gives less fuel, your carbs have the “air screw” on the filter side of the slide, screw in means more fuel, screw out means less fuel.
