Thanks, Mike. Those bigger bolts make sense now. Never occurred to me that the EME engines used a different size. As for the single-bolt adapter, I'll probably just drill and tap a second set of holes in the hub for it. The warbird that this starter will end up in has a radial cowl, so the 1/8" added length (not 3/8") won't really matter. All of my DLE's have the single-bolt adapter and I've become spoiled. The props for this starter are the first props I've drilled in over a year. Good thing I kept my drill jig!
One more thing, Mike. There would seem to be more than enough different ways to screw up the installation and/or operation of these starters as to justify SOMEONE writing a comprehensive instruction manual. Someone with a financial stake in it, as decent manuals are neither quick nor easy to produce. The starter will eventually find it's way into my KMP Bearcat. The P-47 behind it already has one on it's DLE55.
