Flathead pre-oiler - good, bad and the ugly?

[Flathead Fever]

In the real world nobody stakes the time to prime an engine. We didn't do it at the phone company but that was on "their" engines. On my personal stuff I always prime the oil systems before attempting to start them Don't forget to run the new camshaft at the desired break-in rpm for the duration suggested, usually around 20-minutes. I pre-fill the carb and anything else I can think of so that hopefully it cranks a couple turns and lights off. Then immediately take the rpm up to camshaft break-in specs. After the cam is broke then I'll idle it down and adjust the timing and Idel air fuel mixture.
