I own this MotionPro FCR carb tool (here is their link). Notice the blue Sears finger screw driver in the picture - one end allows for any hex bit and the other allows for it to be used with a 1/4" socket wrench. It also has a magnet inside the aluminum blue finger piece so that the bit will stay put. Well, it turns out this piece works perfectly to adjust our Keihin carb's fuel mixture screw and it only costs $1.99 IIRC! OK, not quite perfectly since the bit that it comes with (phillips or flat head) is about 2mm too wide as you can see in this picture where I have my 5/32 bit that has the correct width corresponding to the proper MP's bit to use for our Keihin carb (this is the short bit right above the bottom 2 bits). This is the MP tool with its correct bit for our carb. Here is the Sears' tool with the MP bit attached - noticed that the hex base of the MP bit is just slightly smaller than the standard hex bit setup and there is some play but it works fine inside the Sears' tool. The Sears' tool is very well made, while the MP's hand piece is made of plastic (I think) and is a bit cheesy. I marked the Sears' tool with a Sharpie so that I can tell where the 1/2 and full turn points are (notice the black line - I used 2 lines on the other side to indicate the difference between the 2 measuring points). Here is another picture of the Sears' tool with the MP bit attached - you can use any standard flat head bit as long as the width is not too wide and it will work - I'm guessing the width is around ~4mm wide (my 5/32 bit worked well for this application).

I found the Sears tool the other day sitting on their checkout counter (in a box full of them) and thought this is "perfect" - took it home and it worked out really well! Oh yeah, you have choices of colors too, and I chose BLUE of course

av,

good writeup. but like the French guy atop the castle said in 'Monty Python and The Quest for the Holy Grail', "I already got one". the discovery of the sears tool thing was a circa '00 or '01 thread on thumpertalk. in fact, it may have been james dean or one of the other YZ/WR400 TT pioneers who first posted about it. so of course i had to get one. actually two. and, as you wrote, the sears tool does work just perfectly for the job.

so what's old is new, what's new is old -- you know the drill.

There's always the ZipTy fuel screw which takes out all the pain of adjusting it. The Sears tool is cool for other stuff though, and a great price.
No such thing as "too many tools".

I figured someone must have seen this tool, I bet they didn't post all of the nice pics like I did!

AV,

Old or new, it doesn't matter. You have the pic's, that's what counts
the most.... You win.

I have my screwdriver bit installed into the socket adapter (sorry, no pic).
I then put grip tape around the bottom to help grip with my fingers. I also
put the sharpe marker reference point on the side. It works great. Next
time I go to Sears/hardware store, I'll have to look for the tool.

yeah ok, but there was a pic posted at one time. i swear. really. but i searched and only found this text-only link: an early sears adjuster post.

and this link as well.

all you guys rock anyway.

This is the first I've heard of it.

The shaft of one of those cheapo bit drivers worked on my Yammy but is too long to fit under the carb on my CRF. So far I've been using the bit only, this works, and ordinarily I #@$% hate #@$% Craftsman but that Sears part looks cool for that price.

So thanks for the tip, I'm going to Sears.

like hick, i use a cheapo driver bit.

however, i already had bought the expensive motionpro fcr carb tool. the BIGGEST problem is that the blade on it is too thick and i can't get seem to get it into the slot.

Strange... The smallest bit that comes with the MP set, although somewhat thick, fits perfectly into my 02 carb. Maybe your 01 carb is a little different - I tried my 5/32 bit which is thinner but with the correct width and it worked pretty well (it does have a little play in the slot due to being slightly thinner though), you might want to give a thinner bit a try with the Sears' tool - the MP finger piece won't support the standard hex bits...

Forgot to mention, the other 2 bits that comes with the MP carb set is for removing/installing the pilot jet (i.e. the longer flat head) and the float bowl (i.e. the 3mm Allen head/bit). The MP's finger piece is also used to install/remove the main jet (i.e. 6mm hex) - the Sears' tool will also work for the MJ but will have some play just like how the MP bit fits inside the Sears' tool - this shouldn't matter since you're supposed to hand tighten those brass jets into place (i.e. not too much force).

If you already have all of the above bits in your tool box and you pick up the Sears' finger tool, you can pretty much recreate the MP FCR carb tool set - that's pretty kewl... Cost me $13 for the MP carb tool set, oh well, pass the savings onto you guys/gals...
