Sticking Lycoming O-360 valve again?
I just remembered a local chromed C-85 engine that would "sag" on
takeoff after an overhaul. It was supposedly traced to inadequate ring
gap. I find it hard to believe in your case though after your amount of
time since OH.
You might check the carb floatbowl fuel level with the clear flex
standpipe connected into the carb drain port method. I'm otherwise
outta ideas.....
