Title: D-shaped bit for pilot screw
Post by: Insomniac on July 07, 2010, 09:56:07 PM
I'm getting ready to pull the carbs to add an additional shim and 105 jets (K&N air filter w/ muffler mod) and clean them up (doesn't want to hold much of an idle at all now, have to leave the choke on for a good bit while it warms up even in these temps, flat spot, popping on decel, etc). I know you're supposed to use a D-bit available from Mac Tools to adjust the pilot screws, but is it possible to use something else just to get the screw out the first time so I can cut a slot in it? I honestly have no clue what it looks like or where it's located, so I have no idea if it's worth the hassle of obtaining the bit vs using a heated up butt connector to slide over it or something similar. I mostly don't want to wait for the bit to get here, but if it'll make the job go smoother I will. Any tips?

Thanks guys.

look for 1/4" 'd' shaped bit, this works great.

I ordered it on Thursday, and called Mac Tools on Monday when I hadn't received a shipment notification or tracking number. Turns out, it's on back order :x I ordered the one from Mac Tools specifically (part# MN08-0242) b/c I was under the impression it will work w/ a regular 1/4" ratchet/extension, whereas the one from Motion Pro looks to be a hex bit. Not a big deal either way, really. I don't know that I want to wait until the 17th (when Mac Tools said it should be in, but it's been my experience that those estimates aren't always accurate), so I may just pull the carbs and see if I can make something else work in the meantime.

Holy Cow are all of them that expensive? I was wanting to get one but not at that price.

The bit itself is only $3. The link Chad in Michigan posted is for the special tool that holds/includes the bit, as well as many others. So, no, I don't think you have to buy the $90 tool just to use the bit.

www.mactools.com has them, will have to sift through their site for carb or motorcycle tools.  Thats were I bought a few.  The 90° tool is not very good for the price, dont buy it.  If your in the metroplex you can borrow mine if ya wanna give the nice shiney blue tool a test LoL.

Which 90 Degree tool is the best to use?

I just ground a slot in the screws and use the 90 degree tool.

Finally got mine in the mail from Mac Tools today and, surprise surprise, it's actually the Motion Pro bit. Says so right on the package. This is kind of a bummer as I was hoping it would be a regular 1/4" bit instead of a hex bit, but it will still work. If I had known this I would have just ordered it from Motion Pro to begin with.

That's why I posted the link... I got mine in 2 days from motion pro...

I've got one of those ... it's a little difficult to get properly situated on the screw but it does work.

You can use a regular 1/4" socket hex socket to hold the 1/4" hex drive d-bit.

Yes, I believe it fit directly onto a 1/4" drive screw-driver handle that I've got in my took kit.
