De-winterizing

[Wolfeboro Matt]

I had my O/B professionally winterized last fall (which is basically having all the water drained and getting it "fogged"). I've heard that I merely need to start her up, let the "fog" (whatever that is) burn of, and then replace the plugs. Is it really that easy? I tried it myself a few years back, but it made so much smoke I was worried I wasn't doing it correctly. I had a full tune up last spring so am thinking I could skip this year...

Thanks!
