I agree....
I agree with Derek.....the oil is to provide a moisture barrier on your idle bearings.......the exhaust ports are up high, actually above the carbs, so...I'm sure it didn't run out.
The oil in the bottom of the crank casing won't hurt a thing. Do like Derek said, then when all the oil is about expelled, put your plugs in and fire her up........but like he said, if you want to see some smokin........here's where your gonna see it!.......
When I built my 787, I used Lithium to keep a good moisture barrier....my neighbors thought I was spraying for mosquitoes.........:rofl:
