Well my engine is just humming (roaring?) along. I starts
every time, runs till I stop it, and it doesn’t sound like it is missing
or “hunting” – RPM is about 1400-1500 with the prop on. All leaks are pretty much gone except
for a persistent “weeping” on the oil level sensor on the pan that
produces a drop over 8-12 hours but never drips? It looks like the only way to fix that
is to drain the oil and remove it and maybe the pan, and hit with some RTV.
I’ve run it now for about a total of 30 minutes in 3-4
different runs all of them under 2000 RPM – essentially at whatever I
could get idle to be. The MicroTech is performing
well. However, the Laptop Software what gives a graphical view of the Maps and
the ability to log data requires more than a serial-cable to connect to the
ECU. Apparently they sell a separate little gizmo (“dongle”) that
goes between the laptop serial-port and the serial-cable to the ECU. So I’m
stuck with the 2 line handset for now.
Anyone have any more suggestions on break-in tasks? I
re-read some archived posts on the subject. It sounds like I should keep it
under 3000RPM for the first hour or so and then move it up. Beyond that, and with no more leaks to
fix, I’m at a loss to know what, if anything, I need to do. I really didn’t
expect it to be this easy.
Before first flight I want to have at least 10 hours of
ground running done with at least 1 hour at or above 5000 RPM – and that
1 hour can’t be the last hour.
Should I be checking compression every so often? Timing? Tear the engine down and Mic
all the parts J ?
