All I wanted to do was unscrew...

I got that carb out, and started to take the top cover off of one carb, and the darned screw stripped out. Proper sized screw driver and everything.

Now, I'm some sort of genius when it comes to getting things apart, I'm sure I can finish the disassembly. It's putting it back together that worries me. I can't find replacement screws for most of these parts. Nor straight up replacement parts. Suggestions for these screws?

I also don't want to pour five grand in new parts into my project. Sorta defeats the purpose of doing it yourself.

probably 4mm tread, I go to the hardware store and get stainless allen heads. loews may have them.

Thanks I was worried that they'd be specialty or proprietary screws. This carbs being a right pain to disassemble, by the by.

I assume you are referring to the vacuum diaphragm piston cover or the float bowl cover on the carb. If so, you can always remove the screw using vice grips and while it is out you can slot it for a standard screwdriver. When you assemble the carb, the screw will work just fine. You can always get new and replace when you remove the carb next time if you can't get new screws before assembly.

The trick to removing the screws on the carb is to place the screwdriver into the slot and wack the handle (into the screw head) lightly with a mallet to break the grime/corrosion/etc. that holds the screw so tight. Then, push really hard into the screw with the screwdriver while simultaneously turning it. The screws can get really frozen and the heads are not too strong. I know this will not help you now, but it might help someone else in the future.

I have found that right before the screw begins to strip, I wet the tip of my screwdriver and dip it into a small container of powdered laundry detergent. (Can be any detergent but I have laundry detergent) This adds a little more "grip" for the screwdriver head. Again, too late for your application but could be useful for others.

[Alan Naylor]

I'll remember both tips for the future. And I did end up using vice grips, but those screw heads are gone.

I have the smallest Vise Grip made. They work perfect for this issue. I always start loosening these screws with an impact driver. This tool has a spring in it and always you to preload downward against the fastener. It is made to be stuck with a hammer as you push down and twist. You may also just push down and twist. You can by one at Sears. They all have a half inch square drive which alawys sockets to be used with it or the adapter that is included with the screw bits. http://www.sears.com/shc/s/p_10153_1...ABTestAvl=true

this is what you can use for a replacement, you should be able to get them at any good hardware store, 4x7 I use the 10mm lenth with a ss split washer for the vacuum diaphram, the 14 with a washer for the bowl, the 12mm are hard to find usually special order online. I dont recommend the button heads, the allen key dosnt go in deap enough for my liking. these are what you want http://www.allensfasteners.com/detai...oduct_ID=70475

When you unscrew some of these things, lots of pressure on the screwdriver really makes a difference. You can sometimes unstuck a stripped screw by pressing hard into it.

Use a container of valve grinding compound. It is abrasive and will allow the screw driver to grab well. dip the tip of the screwdriver into the compound and insert in the screw. I have removed THOUSANDS of stuck screws this way without camming out.
