Tried to complete Van's AD for tipup 7's and 9's this AM, got frustrated and went to fly after lunch. South Westbound holding my 50 mile radius for River Ranch( my home field per the limitation) and 10.5k. Followed the circle on around to Lakeland, then climbed to 11.5 eastbound just north of R2901 then south between the build up that looked like they went above 15k. When I ducked down between the clouds to get under, actually got into a light shower (no harm to Ed's prop :>)). Seems like the combination 9 and rotary just like it better the higher I go. Will have to borrow and O2 bottle one of these days.

The only thing that made me uncomfortable today was that when I throttle back to stay out of the red arc on the A/S to about 15 manifold pressue, the engine goes into the unstable up and down hunting that no mixture ratio seems to fix. Any ideas??

Bernie, 13+ hours now.
