Interesting couple days - been having carburetor issues on the right side on my '68 coupe. Was not getting a proper "squirt" from the two discharge holes at the accelerator pump needle valve. When trying to push a .016" wire thru the holes, I found the upper one to be plugged?! A couple months ago I had soaked the upper & lower carb bodies in the Berryman Chem-Dip, rinsed them in kerosene and blown out everything with compressed air. Apparently, that was not enough to get the ?#&* out of that little hole. Wire kept bending while trying to push thru the hole so I thought about a drill . . a VERY SMALL drill! Eventually found circuit board drills on Amazon and had them delivered this morning. 3 of the same 10 piece drill sets for about $14 delivered overnight! I will have small drill bits forever!!

Always fun (a challenge) working on my Corvairs?!! ????

Took a couple photos . . . .

WOW!
Some of those are actually a little on the small side.

WA. state, 1 mile south of the Canadian border, I am not at the end of the world, but you can see it from here.

Hope you checked Bob Helt's Rochester book to use the correct diameter drill for the accelerator pump holes.

I thought that's what torch tip brouchs were for. Nice set of bits though.

Yes, a quick run-through w/ tip cleaners and my accell pumps were tippety-top.

Tiny torch tip cleaner use here too. Really shows you the angle of the squirt too.

I bought some tiny tiny drill bits too over the years (a set of 61 -80 in addition to metric) but yours are pretty! And I have used them to open holes in circuit boards when the component leads (remember way back when parts had leads?) we bought were larger in diameter than the holes speced by the software.


Joel, I "assume" the 10 piece set:

First, let me say that I have a lot of history with small drilling - I built architectural models for 22 years and during that time also worked with a company (group of automobile engineers) in Houston who were automobile crash test and litigation experts - on behalf of Ford & Toyota. Our company made courtroom exhibits - cutting down vehicles, building foam core full size vehicles for on the road accident scene recreations and other courtroom exhibits.

Here is a description of the drill I purchased on Amazon:
