Going back to basics can you say what speed you were climbing at and what the
rate of climb had dropped to by FL100?
Is your ASI set to IAS or TAS? This is in the settings somewhere and should
be IAS. The TAS option is daft - they never should have included it.

Bones,I eventually closed my cowls at about 7500' with my uneducated guess
reasoning that it would be colder up there,possibly more damp and that I need
warm engines:but then I had been on full throttle all thro the climb so presume
that was something I didn't do right. Fred

Or else you can cheat and turn AutoMixture on - but it's best to do it
the proper way.
I'm sure someone else was using the BE58 last night and got well above
FL100. Did you have the cowls open or closed?

Using the Exhaust Gas Temperature (EGT) method, lean and watch EGT it
should start to rise. Your ideal mix is where it peaks so when it starts to
fall again increase the mix a tad and your there.

Fred,
I'm sure I'm not the expert on this, but as I understand it, the
higher you get, the thinner the air gets. The engine sucks in a mixture of air
and fuel, so as you get higher it needs less fuel as there is less air about to
keep the mix in the correct proportions. I have heard of 2 ways to do this, one
is to monitor the exhaust temperature, and the other is to listen to the engine
as you reduce the mix, and when it starts to cough then give it a touch more to
keep it smooth.
Of course, when you descend you have to reverse the process.
