I am hoping that someone may be able to confirm whether the combination of a IO-360-M* (M1B, etc) and a Whirlwind 151 3 Blade CSU (http://www.whirlwindaviation.com/series150.php) is an approved combination?
For my -8, I want 180 hp, the smooth cowl that comes with a horizontal induction, and I like what I am reading about the 151 CSU, but I don't even know what I don't know about engines and prop configurations.
The whirlwind aviation site has a callout that says "Restriction: The 151 Series is not recommended for use in O-360 or IO-360 applications unless the engine is equipped with a counterweighted crankshaft."
Does that rule this specific configuration out? I recall the IO-360M does NOT come in a counterweighted crankshaft configuration? If so, what other choices are available that might let me realise the smooth cowl/three blade CSU combination?
This is all very new to me so sorry if I'm asking dumb questions...
