Pulled the 914 out to wash it, and thought I caught a whiff of raw fuel—but it's an old car and carbureted too. So I let it idle as I rinsed the car, having just started it.
I tend to forget I'm smell deaf, as my better half will confirm. So when I smelled it again, I looked down only to see gas in the water on the driveway. Yep, shut it off immediately. Both carbs leaking gas at their bases. They were resealed a few years ago, and I use Sta-Bil. Ah, you gotta love old cars...
