The fuel mix cap (gasket) on my chainsaw was leaking. I'd filled it just a couple of weeks ago for about 5 minutes use, then today found about 2/3 tank of fuel in the bottom of the carrying case.
Unfortunately it's bigger than any garden hose or other plumbing rubber washers I could find here around the farm.
With some tedious use of a razor blade I made another gasket from an innertube. It has stopped the leak, but I'm concerned how that will hold up to the fuel. A little rubber shock absorber built into one of the handle attachments has turned noticeably gooey by the leaking fuel.
I have some sheet cork that I could use. But wasn't sure that would seal the fuel, or permit it to ooze through.
What say ye? Will the innertube mat'l hold up? Or would cork work better?
Haven't checked, but my guess is the Stihl folks will only sell the gasket as a component on a new fuel tank cap. Not an expense ranking up there with a house mortgage, but still if I can fix this .... Plus, it's just more fun to fix things than to buy replacements.
