Flyboy,
I haven't been in this hobby for 25 years, but I do have an OS 40FP that was in my trainer and a lot of planes since. Have always run the fuel out at the end of the day, and can still start the engine with one flip. I believe it has more power now than it did 8 years ago, so I don't think the 1 second lean run has hurt it.

I guess we just do what works for us.
