Flying requires maintenance. And that's where I am... well have been, because its almost done.
UL Power requires the following at 15 hours
- Change oil and filter
- Check valve lash
- Torque cylinder heads
- Clean course (pre filters), change fine filter.
- And check everything else.
Good chance to go through everything.
To get to the head bolts you have to lift the plenum... and I thought "DAMN". I thought I had built them not removeable... alas no. 6 bolts / screws and they lifted off (plus the plenum tops).
Everything has gone swimmingly. All the valves needed some tweaking, and I got a nudge out of around half the head bolts.
All the spark plugs look good.
No chaffing or other badness.
Ran the engine today after everything to check for leaks. Nothing. Cowls back on and ready to go flying again.
One of my facet transfer pumps (between the aux and main tanks) decided to pack it in. Two new ones ordered.
