Sheesh - Some days.
I headed out to CAT4 early today to get a good morning's work done on the Little Plane. I drained the oil then discovered that the wrench I bought to get the old filter off was too small. No way it was going to budge by hand. So, I added clean oil anyway and left the filter for the next change.
Then I pulled and replaced the spark plugs. I have to wait to install new cables because the Auto Supply store didn't have them in today, though they'd promised them yesterday. Hmmm.. Does two half-finished jobs count as one?
So, it's on to job three - replace one of my batteries. My engine has electronic ignition and electric fuel pumps, so I built it with two SLA "motorcycle" batteries. This also ensures that I'll always have as much time in the batteries as I do in the fuel tanks. If the alternator were to fail, unnoticed, at the beginning of a trip, I could still safely continue to destination. Assuming of course that both batteries are in good condition.
Out comes the old battery - I said, out comes the old battery -- oops. The POS terminal bolt is corroded and breaks off during removal. Not a big deal except I was counting on re-using this part for installation on the new battery. I saved 10% on a 10% stronger battery, but the trade-off was that it was missing the terminal bolt. D'OH! Three Half-Jobs now done.
Then as a way of emphasizing that the Universe was out to get me today, while I was re-installing the cowling, I felt a sharp sting in my finger. I was reaching into a vent hole while wrestling things into position. At first I thought I'd jabbed myself on a sharp edge, but when I looked closely there was no visible cut or puncture. Then I saw a yellow-jacket wasp stumble out of the vent opening.
I was just happy that he was a loner who'd layed up inside the intake for the night - at least I didn't see any evidence of nest-mates.
So, tonight I'm licking my wound and plotting how to finish at least the ignition cables and battery installation tomorrow. Sometimes it's half a step forward and ... I guess that's enough.
