I don't think it would bother too many on this forum. Who has ever bought a brand new aircraft? Luxury taxes don't apply to 2nd hand (or 23rd hand) goods.

I call BS on that statement. I saw the plastic coke bottle float slowly up and kiss the roof. The aircraft would have been pulling just a tad over 0 negative gs. I have seen much higher gs negative...

Bendy,


My post wasn't about rich or lean mixtures. It was about incorrect timing for a particular fuel and how the head could get hot enough to cause valve recession. Without good data relating...

AEFR


Not necessarily. If the octane rating of the fuel is high enough it won't detonate. However if the timing is too far advanced ie the fire is lit too early all the fuel will be burnt at or...
