Default engine pre-oiler

Yep in some ways the accumulator looks good except it does take up a bit

Yeah, and useless if you forget to reset it during shutdown, and limited to
about a quart of prime.


A quart of prime would be six or eight times as much as is needed
to preoil the engine. My little hand-pump on my A-65 does it with ten .
75 cubic-inch strokes, for 7.5 cu. in. total. A larger engine might
take 10 or 12 cubic inches. An engine tighter than mine (61 years old
now) would take much less.
A quart has just under 58 cubic inches.
