mid-morning radio watch and spark plug swap

Kevin returns from the dock and sets up the shortwave on the porch table, tuning to 8291 kHz. Jenny sits beside him with the spare spark plug, a feeler gauge, and the socket set, ready to clean and gap it before swapping it into the Yanmar for a hot idle check.

No narrator was available, so nothing about this stretch was recorded.

Check the gap first, I want to see if it was fouled.

Wipe the carbon off the electrode with the wire brush and use the feeler gauge to measure the gap.

💭 peek at the thought

If the engine fails again, I can't get to the north ridge for the samples.

Zero-eight-two-niner-one. Radio check. Any traffic, this is Sorrel Island, over.

set the shortwave on the porch table, extend the aerial, and tune to 8291 kHz, keying the mic for a radio check

💭 peek at the thought

She's already got the feeler gauge in hand. Good. Means she's not waiting for me to tell her how to do her job.

Sorrel Island, this is Jenny. Copy you loud and clear, over.

Listen to the speaker for a response from the mainland.

💭 peek at the thought

The static is heavy today, maybe the humidity is spiking.

Kevin — take the spare spark plug from the table, brush carbon from the electrode with the wire brush, and check the gap with the feeler gauge

💭 peek at the thought

She's running the radio check for me. Habit from the medevac drills. I'll take the plug while she listens.

🌿 Jenny12:51

It looks okay. Is the electrode burnt out?

Watch the gap as he slides the gauge in.

💭 peek at the thought

If that gap is too wide, the engine won't catch properly.

🔧 Kevin12:51

Electrode's worn, not burnt. Gap's point-nine. Spec's point-seven.

slide the feeler gauge through the gap to show her the reading, then bend the side electrode gently with the gauge edge to close it to 0.7mm

💭 peek at the thought

Electrode's worn but not burnt. Gap's wide at 0.9 — spec's 0.7. She'll want it exact.

🌿 Jenny12:53

Fix it before you put it back.

Watch his fingers bend the metal.

💭 peek at the thought

Point-nine is way too wide for a spark. I'm surprised how it ran that long.

google/diffusiongemma-26b-a4b-it

🔧 Kevin12:53

Kevin — bend the side electrode carefully with the feeler gauge edge, re-check the gap until the 0.7mm blade slides with slight drag, then set the plug on the clean cloth

💭 peek at the thought

She's watching close. Good. Means she'll catch it if I rush.
