| Subject: | Baffling for cylinder cooling |
I built my 701 from plans in 1994/95. It is powered by a Rotax 912 covered
with a Zenair cowl without any internal baffling as per the Zenair
demonstrator and recommendations at the time.
The engine now has 490 hrs and is still running smooth and strong; I see no
difference in static RPM since first flight. I am concerned about two things
however:
1. Front Cylinders head temp is much cooler than the rear;
2. Compression on the front cylinder is 20 lbs less than the rear. 115 vs.
135. This has existed and remained steady since first annual in Nov 1995.
I suspect a cause and affect between these to parameters.
My questions to the list is:
I know of two other 701s that have the same cowl set-up and have never
seen a 701/912 with baffles. Is this the norm?
I'm considering investigating the reason for the lower compression in
the front (vales or cylinders) and designing some baffling to equalize the
cooling. If I just correct the cooling could this destabilize an engine that
is running well?
Any comments appreciated.
Carl

| Subject: | 912 Cases needed |
I am looking for a pair of Rotax 912 engine cases that are JUNK. I need them for
a mock-up. They can be crashed, cracked or what ever. The only part that needs
to be there is all the mounting bosses on the bottom and the rear of the cases.
80HP, 100HP or 914 for that matter, it doesnt matter to me. I can be reached
