I had 4 engine failures with a Cuyuna 442 in fifty flyimg hours, and 10
engine failures with Rotax 447 in the next 200 hours. The reasons didn't
always have to do with 'reliability'; causes included fuel problems,
clogged filter, broken electrical wire, etc. The point is, with 2-strokes,
you have to fly with your brain in gear at all times.
The old Cuyuna 442 had problems with cooling because the air blew straight
back through both cylinders, so the back one didn't get cooled as well. We
solved that by simply tuning it so that it wasn't running on the edge of a
meltdown. Also, the 442 was beefier and hence heavier than the Rotax.

The real problem was the old ignition timing, which was impossible to set
right. Electronic ignition should have completely cured that. Cuyuna also
used a Mikuni carb, vs a Bing for the Rotax. Movavi video converter activation. There were more arguments
about the relative merits of the carbs than of the engines. The carb is
REAL important. Does sony vegas pro 12 work on mac.
