Title: Making your own gaskets
Post by: McCabe-Thiele (Ted) 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've measured a fragment looks like its around 1.25mm or thereabouts compressed down to 1.0mm.

Post by: 350Simon on August 10, 2022, 12:12:02 PM: 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.
