Good morning guys.
G-OWWW is a classic tri-gear with 912S and Airmaster.
I have noticed recently that in the cruise (5000 and 25 MP) every so often
the engine "mumurs" as if one cylinder misfires. It is hard to hear and
happens every 2 - 3 minutes or so. It is just a blip for a fraction of a
second. The rest of the time it runs sweetly at 16.4 litres an hour and 125
knots indicated.
The airplane has done 40 hours now.
Has anyone had this experience ? Has anyone any ideas ? I have heard it
suggested that it is carb ice forming and then dislodging.
My cruise is usually at 2000 - 2400 feet and the external temp has been 15 -
15 Celcius (60 - 65 Fahrenheit).
As you can imagine it is a little worrying :-) As a result I haven't taken
it to France yet.
I should do more tests, with fuel pump on, and others. Any ideas or
suggestions (polite please)
