carb bowl gasket - what material to make one of?

[Andrew Vanis]

Looking for recommendations on gasket material for the carb bowl gasket. - ideas?

I get to play with a laser cutter and thought it would be fun to make some as needed and not have to wait to order one if I tear one.

Also, with the laser cutting tech, I can cut other gaskets - just scan one in and draw it in a cad program. Thinking that head and cylinder gaskets may be next. What material would be good for those? Could even do one for the chain tightener.

Auto parts stores sell gasket paper. Measure the thickness of a bowl gasket and then match the thickness. Get material that resists gasoline of course.

I wouldn't take the risk on a base gasket. The gasket material is thin and of a specialized material that can take the compression forces of that application. Base gaskets are cheap too. Head gaskets are not cheap but they are very specialized in terms of material and construction. I would definitely not attempt to make one of those.

Cheerios boxes work great.

Cheerios boxes work great.

For two minutes?

Decades .

Either your cereal is packaged in something else or cardboard is gasoline-resistant, which would be new to me.

Not that I ever checked the latter.

You might not want to re-use it after decades, but it probably won't leak.

Gasket paper is more durable than a cereal box paper but the bowls shouldn't really be getting all sloppy wet. When you buy bowl gaskets, they can often come in a variety of thicknesses depending on who made them for the same application. Even super thin gaskets will work fine if the gasket mating surfaces are cleaned of all old gasket material and are smooth. The cheerios box material will likely work fine. I wouldn't use it for anything that had some pressure to it like on a crankcase (cylinder head, etc.)... can't say I would try so I don't really know.

OK, a long time ago I made a gasket to go between the the bell housing and the transmission of my Opel GT.... Out of a Cheerios box. It didn't leak at all. Not gasoline, but gear oil in there. Drove it a few years, sold it to someone else, who also sold the car... Ten or so years later I was pulling the transmission out of a long dead Opel Kadett station wagon that had sat in a field for years. Paid the man $50 or whatever, crawled under there and pulled the transmission. And it had my old Cheerios box gasket. Apparently someone bought my old GT for parts and put the entire engine/transmission in this station wagon. And it still didn't leak.

Oh this is pure gold.

I personally prefer Special K boxes.
