Hi guys,

We are getting an engine miss in a Rotax 912-powered a/c. It is fine
until about 20 minutes into the flight, then you can detect the miss.
Strange given that it has dual ignition,. We tried fiddling with the
carb and leaning the mixture off seemed to solve the problem for a few
hours, but it back worse than ever. The ignition parts are quite
expensive so would like to isolate the problem before replacing
everything.

So what I am looking at is advice on testing the ignition coils. How you
should go about it and what equipment is needed. If they check out,
then the modules will be next, but one thing at a time.

Any advice appreciated.

Martin

Any chance you have a misplaced gas line that is vapor locking after the
heat gets to it.....!!
After "....20 min's", it is usually a heat related problem.
