"Tweaking": US term for tinkering things into a more precise
condition... Unofficial definition, of course.
What I did: Basically it encompassed working to improve the whole
airplane. Fine tuning the engine, mainly through the carbs. Working to
remove any vibrations, such as balancing the prop, etc. Filling gaps
around the wing fairings, wheel fairings and LG fairings, covering pip
pin access holes. Testing for power settings that gave maximum speed
and still maintained optimum fuel efficency. I found that, with the
airmaster prop (on the 912S), 27.5" - 28" MAP @ 5000 rpm yeilds right at
130 kts and still maintains the fuel consumption at, or below, 4.5 US
gal per hour.
Don't know it this answers your query, Duncan, but it's what worked for
me... ;)
