Sorry to hear the ongoing struggle Glenn.
I have minimal experience with the IGSO-family, and that little time was with Morris literally smashing my knuckles when I was about to do something stupid (a move typical to my non-geared, non-supercharged engine experience I had prior) to the gear box or keeping the cylinders attached to the plane.
I was always paranoid about LOP but understand the concept and cooler operations so seems you're doing the right thing. But I'm still a bit paranoid about LOP (in any airplane, C310, Mooney 201, 231, AC, T210). Like DonV says, aybe youre getting out from under the deferred maintenance of Moe's tenure (nothing against Moe everyone!).
I'm with DonV. Keep with it, maybe you're close to getting over the hump on all the issues.
At the same time, sounds like Adam is throwing out an offer worth thinking about if that is within your budget/operating conditions at this point in life. Guess he wants one of those 690's at Eagle Creek or something ;-)
Would love to see the posts you're back to your low-no problem flying ways in what you know is a superior plane to the 310 or other platforms (coming from an avid 310 fan but love the hell out of AC's way far over the 310). IT is so much fun following your travels and experiences.
$0.02 from a "wanna be" AC guy!
