So you start your take off roll w 0 flaps, pull the first notch @ 70??
Also you said use all the runway
93kilo- the text you refer to is under the section for "short / soft field takeoff", and yes, that's what I do- accelerate without the drag of the flaps, then add the first notch to levitate off the ground. I wouldn't reccomend that approach unless you're pretty comfortable with the airplane, though, as you have to lean pretty far forward to reach the flap handle, changing your view of the runway and possibly shifting your weight on the rudder pedals. The opportunity for disaster definitely presents itself. Having one of EZFlap's contraptions would make this much less of a concern.
And yes, "use all the runway" means don't give up the 50ft between the taxiway and threshold- backtaxi as far as you can. The subject of running shortfield takeoffs has been covered elsewhere.
As far as climbing out, I was taught to magimize rate of climb with a straight-ahead climb until reaching 500' AGL. Any engine failure below 500 AGL is a straight ahead landing-don't even tempt yourself with the "impossible turn".
Disclaimer: Most of what's in my checklist came from the Stinson POH, but there are some personal modifications. And I am NOT a CFI.
As far as Franklin pistons- they are made by ECI and can be had. Susan Prall from A1 Services in TX periodically places volume orders. Cylinders could theoretically be had from the TC holder in the Czech Republic, but I don't know of anyone who's gotten any. Quality overhauled cylinders are available from a number of sources.
