QUESTION: I have a question on my IGO-540-A1A, an engine with a rated RPM of 3,400. When it comes time for an overhaul, S.I. 1037K calls for intake valve LW-12949.
For those of us who reside in northern climates, it’s time for us to begin thinking about what we need to do to get our aircraft ready to put in the barn for the winter.
QUESTION: I have had instructors insist that I lean the engine while taxiing my O-320 Lycoming.
QUESTION: A friend has an O-320 in his hangar. I have only the following data, and am wondering how or where I can use these data to determine exactly which engine this is. Data plate says: O-320, eng #2689-27. The case is cast with the number L-17001-27A. I tried using the Lycoming website, hoping for a serial number lookup table, but so far no luck.
I have a Lycoming O-320-D2A that will be going into a Wittman Tailwind. The crankcase and crankshaft are yellow tagged. The camshaft is really pitted and will need to be replaced. I imagine the followers will need replacing also unless refurbishing them isn’t a big deal.
I have a high-wing homebuilt aircraft into which I have installed an IO-360-A1B 200-hp Lycoming salvaged from a Lake Amphiban, with 660 TT. My problem is that it makes loud popping noises at low RPM, such as when landing or taxiing. I have a cross-over type exhaust, and have had a mechanic check both the exhaust and the intake for leaks, but this is not the problem. Do you have any idea what else might cause this problem?
I own a 1962 Piper Colt with a O-235-C1B engine. My operator manual says that I should have 115 hp at 2800 RPM. At what point would I achieve highest RPM? On takeoff? Level flight at full throttle?
Cessna 182s have been burdened by a 1,500 hour TBO for many years. However, the O-470-U engine is now available with a 2,000 hour TBO. What possibly could they have done to the engine to extend the TBO by 33%?
I have a Lycoming AEIO-360 in my Pitts S1S. I have been running AeroShell 100W Plus for years. Some buddies I fly with have been using an Amsoil oil (I’m not sure the number). What is the best oil and weight to run in this engine?
How about a discussion of the scalloped wheel on the injector pump for an IO540-C4B5 engine? My engine will “”load up”” at idle and I have to run the rpm up to about 1,200 quite often during taxi. Also the engine will “”talk to you”” on final with the throttle closed. I have tried the idle cut-off procedure looking for rpm rise, but this doesn’t seem to help.
