aerosport power also has some nice manuals ("Reference Library") for free on their website. they're about the best quality engine docs i have found online.

still cannot believe how many aviation companies charge for their manuals (despite customers paying big $$$ for the products already)...
definitely a sign of "old economy".
in this day and age, having free access to install manuals and spec sheets should be standard.
