It there a tool for adjusting the pilot air screws that fits for use on the left side carb?

How do you adjust it ?

Fuel screws, not air...OEM Keihin pilot screw head uses a "D" socket bit.

You can get a piece of brake line and flatten one side to make a D tool. I took mine out with needlenose pliers and cut a screw slot in them to use a flat head screwdriver. They are also available with a screw head to buy.

Call them what you want they adjust the fuel / air ratio or air / fuel ratio. If you google either or "pilot air screw" or "pilot fuel screw" you'll get the same pictures ! I just happen to use MINE to adjust the air / fuel and NOT the fuel / air mix.

Yes I know they are the "D" head style , I have the bit. there is barely clearance for the adjustment on the left side carb.

I'll call them what they are, thanks.

I made a tool out of a 223/.5.56 empty casing, after I got it formed right, it worked fine. But I moved on and changed over to the finger knurled needles, that Fast Eddy sells. Much Betta.

I used a 22 mini mag casing. Flattened out one side with needle nose pliers. Works great.
