En-Route
Been flying behind a Lyc IO360 regularly for the past few months.
1st for sure event, fueled the plane ran it up, all ok and parked it. Next morning taxied out for departure at 1800rpm mag check was ok, but was just a bit rough and #2 EGT looked a bit off (I think colder than normal). Tried to do a full power run up and above 2000rpm, #2 cylinder went completely cold on both Mags. Taxied back, got injector cleaned and all was good.
About 12 flight hours later and a month later had almost the same thing happen on the #2 injector
Cleaned the injector and swapped it with the #4 injector.
About 6 flight hours and 2 weeks later Mid flight the #4 injector plugged again (running very rough), going full rich mostly smoothed it out.
3 strikes your out, That injector is getting replaced (not cleaned again). I always thought injectors were pretty fool proof, essentially a precision diameter and shaped hole to meter and spray fuel. Is there more to it than that, what about an injector would cause it to repeatedly clog?
