| Has anyone made or know of a screwdriver to fit the needle valve seat to a carburetor? I would love to have one. I never seem to be able to find one that is wide enough to fit from one side to the otherof the seat. Dave. |

| I modified an old putty knife to fit and then I can use a pair of pliers to turn it while pushing it against the seat while clamped in a vise. |

Dave, I use a large Snap-On brand screwdriver, it fits in the seat fine.
I have thought about cutting it off and welding a tee handle on top of the bar so it's not as hard to use. You might take a seat to the hardware store and get a cheapo one and work it over.

I bought a set of these 1/2 drive bits from H-F for like $10 when I needed to take the fields out of a starter. The smallest flat bladed one is now ground down to fit carburetor needle seats. If H-F disturbs you about all the tool companies make similar sets.

My Craftsman set has one that is perfect size for the jets.
you can always get a cheep screwdriver that a litle to wide and grind it down. A real auto parts store should have a carb jet screwdriver in the lesly tools they have a little nipple that sticks down into the jet. Mine was borrowed and never came home.

Flat blade metric screw drivers tend to be thinner than SAE. But SAE can be thinned to fit. I'm of the opinion that flat blade screwdrivers should be filed, not ground. I have much better control with a flat file while holding the driver shank in my vice. Had one rounded off yesterday, with a half dozen strokes of a good mill file it now has square edges again. Whether grinding or filing, the closer the faces can be to parallel the better the screwdriver will work and the less pressure it will take to keep it in the slot on a good screw. Gerald J. |

| I use a cheap drum brake adjustment tool. Got the tip on this board about a year ago. Am going to straighten the shaft with the "gas hatchet" and weld on a cheap 3/8 socket. |

I bought a few "too big" screwdrivers from HF and ground them to the size and profile I wanted. ------------- Good judgment comes from experience. Experience comes from bad judgment.

I took an old screwdriver and ground one side flat and ground the blade down a little and use it cross wise to turn the seat out. That way you can get a little leverage on the seats that sometimes have not been removed since they were put in new. ------------- "Yet there are soulless men whose hand and brain tear down what time will never give again."

Take a regular screwdriver that is a little too big and grind the point off of it. Then grind it off until the thickness of the screwdriver is the exact width to fit the seat and then work on the width of the screwdriver if you need clearance on the side.
This method also works for making them to remove jets. ------------- I Love Meatballs and Dumplings on Toast with Gravy and Rosemary and ??? {Open For Suggestions} |

When you get done it will be similar to a cabinet screwdriver. ------------- I Love Meatballs and Dumplings on Toast with Gravy and Rosemary and ??? {Open For Suggestions} |

| For needle seats I ground the sides off of a 3/4" flat spade wood bit and ground the point to fit in the center. It has a hex shank and I clamp vicegrips on it and have had good success with it. Jets, I haven't found a good way yet. |

| ...................On a related note, Briggs & Stratton makes a special carburetor nozzle tool for their "flo-Jet" carbs and others, P/N 19280, price ?; no longer shows up in the parts price list; has 4 sizes and could fit in your pocket. |

| I bit the bullet and bought a set of Forstner hollow ground screwdrivers. No more nicking up the tops of brass jets, they work perfectly. Larry |

| Snap-on makes a screw driver for a special fastner on airplanes part #S6180, it fits the float valve seat and has a sq. shank. I have used a small adj wrench with it serveral times and have not twisted the blade. It is the best thing I have found. |
