I've been making my own gaskets here and there since I was 14
Why run and spend a half a day searching for a dumb gasket when you can make one? I made one last week for a lawn mower and I've made tons for dirtbikes etc. I tried to buy a gasket cutting machine from a failer local motorcycle shop but the owner wouldn't let that go - I talked to him a year after that day and he sold it eventually (for cheap) cause he needed money. Whatever!
