Well, I flew it today for about 45 minutes, first time since the
failure. Ran it on the ground for awhile at various throttle settings, no
trouble, then took off, climbed to around 300' and flew around for awhile
(within gliding distance of the field, of course!). Not a bobble from the
engine. CHT and EGT both where they should be. It's looking like the
float needle was indeed bad and probably caused at least the quitting when
at low rpm's and perhaps the drop from cruise rpm as well. Somebody
suggested that could've been icing, if it iced up at the main jet/needle
where the fuel is atomizing and coldest, it could be sudden, much more so
than icing on the butterfly of a standard carb. Certainly I'll keep a
close eye on it for the next few flights, though...
On a sorta related note, afterwards I went for a ride in a friend's new
Aircam. What a neat airplane! It just LEAPS off the ground, 'bout 100'
takeoff roll... you can take off and fly all day on one engine, so cruising
around low over the forest is no worries... if the engine quits there's a
spare!
