Jeff, and Rough River folks,
I need a vacation bad, so I am bringing my camping gear and driving up
Friday with about 5 gas cans for those who may need fuel and I will
bring a tool box and some basic electrical repair parts for those who
may need a quick fix on something.
Jeff,
Glad you caught the lower NACA, as it is a killer for trapping air in
the top of the cowl.

Thanks Bud and all else!
I have fixed the wire by soldering on a 6 inch or so pig tail of high
quality aircraft wire then crimped them to the Mag wires going to the
switch. I did away with the rotax connectors and per all your advices
tie wrapped them securely so there are no lose wires. All works well.
On my cooling issues it's just a mater of too high of pressure in the
lower cowl not letting the upper air from the top intakes down
through.
Until now the lower NACA was just shooting air into the lower cowl
with
no direction causing the this high pressure. John Hurst told me some
time ago the demonstrator was set up this way and it was fine. This
overheating never showed until this hot Tennessee heat wave hit. Again
I believe I'll have it solved. I have glassed in the lower NACA to
receive a 2 inch scat tube. This I will run to the upper part of the
cowl. I hope it eliminates the high, lower cowl pressure and increases
the top air pressure to force more air cooling down through the
cylinders. I should have it all fixed in time for next weekend's
fly-in at Rough River.
I am looking forward to seeing old friends and some new ones. It's
amazing how many people we all have become friends with over this
forum
and this is a chance to finally put faces to them.
If there are any Europa flyers or builders that have not committed to
coming this weekend to Rough River KY. I would encourage you to do so.
Weather permitting of course.
Best Regards,
Jeff R.
