That's really the bottom line. All we have to do is make sure the thing will restart and windmilling is not an issue in the first place. If the choice comes down to installing a starter and alternator on a Corvair or VW, and keeping it in tune so that it will start immediately, versus spending a ton of money buying and maintaining an official aircraft engine with expensive metal prop, you know which way I'm going. I keep my cars so they start on the first cylinder or so, and I expect my airplane engine (with automotive carburetor) will start every bit as fast. I have an EIS (engine information system) that will warn me if voltage gets low, and an idiot light from the dynamo that will warn me if it stops charging the battery. And I don't think I'm going to shut the engine down in flight on a regular basis just to see what happens. I don't see a problem worth worrying about.
