Default Engine dies mid-air

(It's not a plane, so using that technique for checking high-end rpm won't work)

Anyway, it seems to have helped to richen the engine... Did two flights yesterday, and the engine was running fine.

LOL, I'm not criticising your cleaning regieme! The reason I ask is that the TT36 is known to have a dodgy front bearing seal. A lot will start to leak significant amounts of raw fuel out through the bearing - having a lot of 'clean' looking oil on the top of the tank and inside the frames is an indication the bearing seal is gone. This might tie up with what Howell said, as the tank runs down you're gettting fuel starvation, compounded by the leaky bearing.

Ok, but I don't see how this could be the cause of the problem.
I mean, the engine was running just fine up until the point where it just quit. If the engine was too lean, it should have shown the usual symptoms; no or little smoke, really unwilling to rev up, loss of power, etc...

(I did change all the fuel lines as well, but couldn't see anything wrong with the old ones.)
