First Rotax is the expert and Mfg. They have hundreds of thousands of hours of
actual flight data and testing, not to mention millions of $$$ in testing and
the Mfg of the 912 engine since late 1989.
How much of this do any of us have? Who has the facilities here to run an engine
day in and out and the instruments to collect the data?
Second maybe the rest of the old timers haven't caught up to newer ideas and technology,
which is definitely the case in a lot of GA stuff. If you make a change
you are liable and you have to invest tons of money for testing and STC's.
That's one big reason you don't see big progressive changes in the GA engine
stuff.
If anyone chooses to experiment with their $18.5K engine then it's ok. This is
also where they get good data on things not to do, from the guys that like to
experiment. I think spending $3 on a little tube of heat conducting paste makes
good sense and a good investment.
The plugs don't get hotter. All we are trying to do is make the heads and plugs
heat and transfer of the heat the same. By doing so you get a better marriage
between heads and plugs.
I don't quite understand why people are so reluctant to follow proven practices
from an MFG that cost so little and is so easy. We have all invested so much
time, money and education in our hobby, why stop on our on going educational process.
