I've got a Stihl 025 that's about 20 years old. Just noticed that with about 1/4 tank of fuel left, it's leaking gas somewhere, even after sitting upright and untouched for a couple of days. I don't think it can be the filler cap, the vent line, the fuel line, or the carb, since all of those are above the fuel level when the saw is sitting upright. It appears to be on the flywheel side.
Any ideas where this could be coming from? Could a crankcase seal leak fuel days after the saw has been run? Do these tanks ever develop small cracks? Not sure where the impulse line is tucked away, but it's never been changed, so could that be it?
It's probably only an ounce or so a day, but I keep noticing a little more each time I check by setting it on a fresh paper towel.
Thanks for any ideas,
Jack
