...I told you some of those old parts are hard to get...but y'all wanna argue forever... there's probably some old mower shop boarded up somewhere with a ton of those things in a crusty old box wadded up in a corner on a back shelf and no one will ever know!

Or some old hoarder has a pile of stuff locked away... well bunches in either case...
It's why I stopped messing with those old things years ago...and when you do come across some old coot with a stash of junk they act like it's the last pot of gold on the planet

Yeah yeah, I know. Parts are hard to find for these carbs.
It is cool to keep it on the road though, and ATM it's cheaper than a Mikuni carburetor setup.
Need to get that e tube out today....
-Self Merged-
Modified screwdriver didn't work. Even at the biggest part of the taper it's too small. Looks like I'll either have to grind one of the Craftsman ones or spend about $14 on the OEM tool.
Which is infuriating because I can't transfer my cash to my account ATM!!

Within walking distance from our house, we have a small engine shop that's actually a Briggs and Stratton-certified Diamond Dealer! How cool is that!
I just got off the phone with them, and they have the carburetor screwdriver, but it's the mechanic's and not for sale. I asked if I could take the carburetor in to them to get the emulsion tube removed, but the mechanic said it's not a magic tool, it doesn't really do anything a normal screwdriver can't. They recommended that I just use normal screwdrivers.
So, looks like I'm gonna have to grind another screwdriver!

Of course they did. They don't want to be responsible for uhmm uh "fouling" up your carb, but would be delighted to sell you another.
Do you get why a hollow ground bit is important? Tapered screwdrivers and jets are a bad combo.
How deep is the main jet, will an el cheapo 4in1 not work?
Fun fact, I used to set up Cozzini (hollow ground) knife sharpeners. Made some knife wielding, hard working, meat trimmers very happy. Just a couple of grinding wheels dressed properly and aligned within a couple thousandths. Not that difficult, but I bothered to RTFM. Considered a blow off PM (preventive maintenance) task by others at this plant.

The emulsion tube and jet are one piece. And the slot for the screwdriver is about ~1" down a VERY narrow threaded hole. Only the smaller screwdrivers can fit in there, and the bits themselves from the 4 n' 1s don't fit. It's pretty small.
The cheapo screwdriver I modified was wide thick enough compared to the slot, but it was not wide enough, so it didn't work. The Craftsman screwdrivers are a suitable size for me to modify, plus we have a lot of them.
It's just slow, because we don't have a bench grinder, so all I'm using is a double cut file.

Well, I guess I'd better close off this thread for future reference. I successfully modified a screwdriver and friction lapped the emulsion tube mating surfaces, flattened the upper carburetor body, and put some copper sealant around the vent passage.
Seals tight as a drum!
