We had our first run of the engine. We tested the fuel system first, both the internal pressure, looking for leaks and then we jacked up the plane in a nose high attitude (17 degrees) and did a fuel flow test.

We ran 1 minute on each tank with only 3.5 gallons of fuel in each tank and got similar results of about 2.5 lbs per minute. This is about double what Lycoming demands from the fuel flow test.

Now the plane is finally done! We have just the inspection left and then we can do our first flight!

Here is a link to the video of our first engine test run. I did have a CHT probe and an EGT probe wired backwards (swapped the pins) which was (thankfully) and easy fix so all probes ended up testing perfect after the initial run.
