We adjusted the idle on our engine, as it was idling too low (below 1400 RPM). By turning the idle screw a bit at a time and retesting, we found that a total of 5 whole turns clockwise was needed to get it to 1700 RPM where it was idling smoothly.
We started to do another taxi test, but cut it short because our coolant temperatures were getting too high. We had the top cowl off during this test, so suspect the change in airflow may have contributed to this, along with the very hot outside temperatures (97 degrees). We will retest this with the top cowl on in near future to check this out.
We installed a new bingo fuel sensor that arrived in the mail (since the initial one died on us). The new sensor works great and our low fuel warning light is working again.
We have been smelling some fuel odors in the cabin, but an initial search for leaks didn't turn up anything which was a bit confounding. However, the odor didn't go away over time, so we decided it was time to go on a more thorough hunt for the source. By examining every fitting very carefully and closely, we actually found 2 issues. One was an NPT fitting at the bottom of the header tank. We could feel one area was slightly moist where a little fuel has slowly seeped out. This was tightened to seal the leak. The other issue was at the bottom of the left wing tank, where the fuel strainer screws in. We had to unfold the wings to find this one. The fitting was actually bottomed out in the hole, so it could not be screwed on any tighter. We found a 2nd fuel strainer that had threads cut a little different to fit a bit tighter. We installed this fitting and reconnected the hoses to the wing. Hours: 6
