Larger venturi, better atomization, more precise fuel metering. Modern design that would let the engine breathe properly.
But when I tried to install it, I hit a problem.
One of the mounting bolts had rusted, fused to the engine block.
I tried for two hours with every tool in the barn.
It wouldn’t budge.
I’d need help.
Equipment I didn’t have.
Which meant going to Mrs. Finch.
I rode my bicycle the three miles to her house, hot August sun beating down, my shirt sticking to my back.
She was in her workshop, torch in hand, working on something for a customer.
“I need to borrow a heavy-duty wrench.”
She raised her face shield and looked at me.
“What kind?”
“The heavy-duty kind.”
Her eyes narrowed.
“What are you working on, Goldie?”
I didn’t answer.
Couldn’t make myself say it out loud.
“You’re touching the John Deere, aren’t you?”
My silence was confession enough.
“That’s the stupidest thing you’ve ever tried to do.”
“I know.”
My voice came out stronger than I felt.
“But I have to try. I have to prove I can.”
Mrs. Finch set down her torch and pulled off her gloves.
Her face was hard.
“Prove it to who? That Caldwell boy, your grandpa, or yourself?”
“All of them.”
She shook her head.
“You understand what happens if you mess this up. That tractor is all your family has. You break it, they lose everything.”
“I know.”
“And you’re still going to do it?”
“Yes.”
She stared at me.
I stared back.
Neither of us blinked.
Finally, she sighed.
“If you’re determined to do something this insane, at least do it right. I’m coming with you.”
We worked together for the rest of Tuesday and all of Wednesday.
The heavy wrench freed the rusted bolt.
The new carburetor installed cleanly.
Mrs. Finch checked every connection I made and caught two mistakes before they became problems.
The exhaust modification was harder.
I designed a new manifold that would reduce back pressure and let the engine expel waste gases more efficiently. But welding it required precision I hadn’t quite mastered yet.
My first attempt cracked.
Mrs. Finch made me grind it down and start over.
“Wrong angle. The heat’s not distributing evenly. Try again.”
Second attempt, same result.
Crack in the weld.
“Too much heat this time. You’re burning through. Control your torch.”
The third attempt took four hours.
My hands ached. My back hurt from bending over the work. Sweat dripped into my eyes, but the weld held.
