Paul and Francois, wow that was a great discussion. Paul, you are not
kidding about other systems failing. Today I got off a little early and
thought I would get in a couple hours of flight time. On pre-flight I
notice a loose alternator belt which lead me to a crack in the alternator
bracket. The thing was just hanging on by a thread. All I had to do was
loosen the tensioning arm and the alternator fell off all together. (BTW, I
had previously taken your advise and replace my alum. tensioning arm with
steel) It turns out the weld was of very poor quality and the design was
marginal. I paid top dollar to some guy named Neil Sherm, who is also the
guy who sold me the rusted out 13B.
Anyway sorry I don't have any pictures, but I already dropped it off at a
welder I know and trust. We will also be improving the design with a couple
of gussets.
Francois input has encouraged me to make sure that I do some fine adjusting
of my timing as soon as possible.
I will be keeping my MAP under 30 except for take off for the duration of my
flight test period. This will still yield quite a brisk cruise speed at the
higher altitudes after I get a prop that can handle it.

I got a picture of your old tensioning arm and I can probably dig up
the discussion we had on it if you want me to :)
