We tried every socket, wrench, and tool in the two hangars. They were all too short. Nothing would reach the damn sparkplug. Complicating the issue was the fact we couldn’t be 100% sure what type of socket we needed. It was clear that the three quarter-inch was too small and the one-inch was too big. But unlike Goldie Locks, in the world of socket wrenches there’s more than one bowl of porridge to choose from once you rule out the bowl that’s too hot and the bowl that’s too cold. In between three quarter-inch and one-inch stand 13/16, 7/8, and 15/16.
Seriously? Why on earth do we need so many nuts so close in size to each other?
Still, clearly, to shoe the horse, to get to battle, to save the kingdom, we needed a new nail. Well, I guess we had the nail. We needed the damn hammer.
It was the weekend; the local True Value hardware store was closed, so we hopped in the car and went to the nearest truck stop to see if we could buy a better tool. Believe it or not, there are three huge truck stops in town: A Love’s, a Pilot, and a TA.
And none of them carry socket wrenches big enough for sparkplugs.
“What the hell kinda of truck stops don’t have tools for sparkplugs?” fumed Lisa.
I don’t know much about engines, but one thing I do know is that diesel engines don’t have sparkplugs, so there’s no reason for truckers to need tools to remove plugs, hence no real reason for a truck stop to carry such a tool, other than the fact it would have made my day much easier.
Next, she called her adult son Adrian, owner of many a tool. There was no way he could come down to SXU, but he told her his tool box was open to her any time day or night. The problem was that reaching his tool box would require a 3+ hour round trip.
But with the sun now approaching the apex of the day, it was clear that we’d need to take a trip somewhere. The best bet was Las Vegas, NM, a hair over an hour’s drive away. Vegas has a two hardware stores, three auto parts shops, two ranch supply places, and a Walmart. Given all those choices, finding a socket capable of removing the sparkplug didn’t sound like much of a gamble.
We loaded up all of our close-but-no-cigar tools and headed out. And drove. And drove. And drove. And drove.
Lisa decided to hit AutoZone first, as it seemed logical to her that a car place would have the right tool for a sparkplug, even though we accepted the fact that car and airplane sparkplugs might not have much in common. When we arrived we found socket wrench heaven. Sockets as far as the eye could see. Well, not that far. But a good thirty feet of sockets hung on pegs in the middle isle of the long, skinny store. We quickly found the short versions of the three most probable sizes, and then found deep versions. Or maybe they were called extra-deep, I can’t remember. All I knew was that they looked quite a bit longer than the ones we had that didn’t quite reach. Problem solved. Or so I thought. Just as quickly, Lisa discovered that we could buy a whole set of sockets for the price of the three solo performers.
At the last second, as we walked up to the cash register, I realized that our new problem-solving sockets were all half inch “drive.” That meant the end of the socket that connects to the wrench is designed for a half-inch wrench, but all of ours are 3/8 inches. We needed an adaptor to make the whole plan work. I was very proud of myself that I noticed this and saved us a worthless drive.
How wrong I was.
But I’m getting ahead of myself. Naturally, AutoZone didn’t have the adaptor we needed. I guess they wanted us to spend thirty bucks on the wrench next size up. We ducked that bullet by finding the adaptor at the nearby ranch store and left Vegas in high spirits, thinking that we’d have the plug out within minutes of arriving back at the airport.
We drove. And we drove. And we drove. And we drove, arriving back at SXU with the sun low in the sky and long shadows stretching across the landscape. We happily snapped the adaptor onto our wrench, then clicked a long socket onto the adaptor, sliding it down over the narrow shaft of the sparkplug to find…
It, too, wasn’t deep enough.
The socket didn’t reach the nut of the Tempest spark plug that Lisa’s mechanic though was the root of all evil.
Now complicating the issue was the fact that the right mag—the one giving us trouble—is supposed to control the top plugs, suggesting that our issue was a top plug, but there was a good chance that the plane’s ignition switch was wired backwards, with the right mag position controlling the left mag, and vice versa. So we had no clue which of the eight plugs was the problem child.
With nothing to lose, and a wrench that could check all the remaining seven plugs, which were Champs, we decided to pull and check all the others. Given that the right mag was supposed to control the tops we started with the top, removing the sparkplug covers on Warbler’s cowl, which exposes narrow canyons in the metal engine cover that are not quite wide enough to really work on the plugs. (The Continental Engine doesn’t really fit in the Ercoupe; it was designed for another engine altogether, but that’s a story for another day.)
I slipped the wrench over the first sparkplug, and this time, being a Champion plug, it fit. I tugged at the wrench. I pulled. I pushed. The plug was stuck fast like Excalibur in the stone.
“Thump it,” said Lisa.
Like hell. I was afraid I’d break it.
“I’ve watched the guys,” Lisa said, “they thump it.”
Leary of this advice I pulled my iPhone out of my rear pocket and did a Google Search on sparkplug removal. The collective wisdom of the internet was that you should thump a sparkplug.
“OK,” I said, and thumped the wrench handle with my right palm. Pain shot up my arm like a springing Cheetah. “Ow,” I whined, shaking my hand.
Lisa tried next, holding the wrench in one hand, and thumping its handle with the palm of the other. “Ow,” she squeaked.
Not wanting to go down in history as a guy who hits like a girl, I put on a pair of work gloves and tried again. This time, with minimal pain, which I hid behind my macho image, the wrench spun, and in seconds the plug was free.
It was clean as a whistle.
A half an hour later we knew that all seven Champion plugs were clean. Only the single Tempest plug was left. The one that her mechanic replaced two flight hours ago. And the prime suspect in our troubles. The plug that we couldn’t reach. The plug that was causing a storm worth of trouble.
The sun was setting. It was Sunday. Lisa had three classes to teach in the morning, and I was skating on thin ice on a story deadline with one of my editors, and really needed to send the morning writing. But I’ve left something out. All throughout this misadventure there’s been a background radiation of panic. Lisa is on the brink of trying to finish her license. She’d signed up for lessons with a flight school in Santa Fe, in her plane, for nearly every day of the winter break from the college where she teaches. She’s arranged for a place to stay over there, got ahead on laundry and packed clothes, bought groceries, cleared her schedule of any other responsibilities, and hired a cat sitter.
OK. I made up the part about the cat sitter. That’s the great thing about cats, they take care of themselves pretty well if you need to be away for a few days.
But now, all of that was in jeopardy. Her plane was grounded.
Lisa stood looking at Warbler, silent, deflated but not defeated. Not being a woman to give up easily, she rallied. “I going to Adrian’s tonight. Maybe he’ll have something different. Or maybe he can drill out one of these sockets deeper. Or we’ll go to every store in town. I’ll call the college and have someone fill in. Don’t worry about me, I’ll take care of this.”
In for a penny, in for a pound. “Aw, heck… pick me up on your way by.”
The next morning, bearing a pouch of borrowed tools, she dropped by the house and picked up Rio (who by now wanted to witness the next chapter in person, rather than by text) and I up, and we headed out. We brought a picnic lunch, figuring on an all-day maintenance fest, including a possible round of musical sparkplugs to rule in or rule out a mechanical failure on a sparkplug that otherwise looked clean. Debs, who was taking Grandma Jean to a doctor’s appointment in Santa Fe was on standby to bring us replacement plugs if needed. It was hall hands on deck.
Two minutes after we arrived at SXU with Adrian’s extra deep sockets, with a heavy thump of Lisa’s gloved hand, the Tempest in a tea pot was off the engine. It was coated with oil.
After following the cleaning directions—which involved gas sumped from the tanks, a wire brush, carburetor cleaner, and a piece of paper—we towed Warbler out, buttoned up the hangar, and Lisa fired him up.
After waiting, and waiting, and waiting, and waiting for him to warm up, she performed a mag check.
It was perfect.
Problem solved. Or was it? Why did the plug foul with oil so quickly? Did she need new piston rings? Or worse, a new cylinder? In either case, a break-in flight would be required. This was not looking good for the home team or for Lisa’s intensive flight training plans.
Lisa called her mechanic again to report our discovery. “I’ve been thinking about it,” he told her. And he had a theory. He knew her engine was older. Probably the piston rings weren’t the best. But he got to thinking that perhaps with the long warm up times at low RPM during our recent cold weather, more oil was slipping past the piston than could be burned off the plug. He suggested she warm up the plane at a higher RPM and see what happened. He also suggested a post-flight mag check, if the plug got fouled during a flight, it could be cleaned before the next flight. She could clean as needed, at least until her week-long intensive training was done.
So with the problem fixed in no time, and with a picnic lunch and the full day ahead of us, there was nothing left to do but have a plane party.
Then sit back and relax.
The horse had a shoe. The warrior was off to battle. The kingdom was safe.
Until the next lost nail.
