engine pre-oiler
Maxwell: The engine is installed in my Baby Belle helicopter. It has a dry
sump located just below the accesory case and a flat plate replaces the
normal cast sump which contained the intake manifold. A new intake manifold
was constructed, drain tubes made for the valve covers and an oil return was
fashioned connected to the accesory case. Works like gangbusters so far
(230hrs). If you want I could snap a shot and send them to you via e-mail?

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

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.
You got any photos of that rig?
