Making your own gaskets
« on: August 07, 2022, 02:02:19 PM »
I need to make a set of carb top gaskets any pointers as to how thick a sheet of suitable gasket paper I need ?

Links to suitable sized paper would come in handy , unless anyone has some proper  left over gaskets they want to part with ?

I'd say 2-3mm Ted, they are fairly thick as standard.

You can buy genuine Flexoid paper on Fleabay. Not too sure about the suggested 2-3mm thickness, that does seem awfully thick. Having said which, I admit to never having had the tops off of my carbs, so quite happy to be proved wrong. Mike.

I've measured a fragment looks like its around 1.25mm or thereabouts compressed down to 1.0mm.

Get yourself a set of wad punches and punch on a piece of hardwood or MDF.
Where's that 10mm socket got to?

As mentioned above, flexoid paper from ebay is the best, its oil and water resistant and comes in various thicknesses up to about 2mm. Years ago I bought some leather punches, 3mm up to 19mm diameter for all the holes, and to cut the gaskets out you can't beat swiss army knife scissors.
If it isn't broken, fix it anyway!
