Correct "perfect" screwdriver for fuel mixture screws

[jfman]

What is a screwdriver that is known to work perfectly for the idle mixture screws on our carbs?

[MiCarl]

What works well is a 3/16" cabinet tipped screwdriver.

 

I made my own by grinding the sides off the tip of a 3/16" round shaft screwdriver I got at the hardware store.

Like this but I'll have to shave the sides down?

That Klein screwdriver you linked to is what Carl is recommending. He made a 3/16" cabinet tip screwdriver from an ordinary "flared" tip screwdriver by grinding off the "flare".

There will be no grinding involved if you buy a CABINET tip screwdriver. You are not to be working the screwdriver very hard, so a cheap cabinet tip 'driver will suffice.

An example of a 3/16" Cabinet tip driver:

Compare it to a "flared" 3/16" driver: The flared tip will not enter the pilot screw recess, (too wide).

Maybe I just had beginners luck, I found a long screwdriver from Sears years back. No issues...

I made a pilot screw "adjuster" that allowed me to make adjustments to the air/fuel mix while the Venture is nearly fully "dressed" (i.e. with the fairing lowers on the bike, but with the side covers removed. One cannot access the pilot screws with a conventional screwdriver when the lowers are installed).

Went tool shipping yesterday with an a/f mix screw in hand and picked this guy up.

 

JET brand model 720813 works perfect (it wasnt cheap)

e).

 

Two of the 8 carbs I been working on the a/f screw was completely seized. One I got out but another the head of the screw stripped and it's stuck in there forever I guess, never to be adjusted again unless I tackle it with an easy out.

 

For this reason it's important to me that the tip of the blade fits into the slot on the screw dead on with little or no play. That way when you twist on the driver, the whole blade is making contact with the whole slot on the screw, minimizing your risk of stripping the head.
