Episode 308 John Stumpf: “The Self-Made Mechanic”

ATV-TALK A Motorsport Podcast

Growing up on a farm instills a strong work ethic and adaptability—qualities that have been invaluable in Jon Stumf’s journey as a mechanic.

Jon learned to build and repair machines on a farm with limited resources, guided by a father who taught him how to overcome breakdowns and challenges.

Jon’s most valuable education came from working at a dealership, where he gained hands-on experience with a variety of manufacturers and benefited from the mentorship of a seasoned technician.

Jon’s love for racing further honed his skills. He tested his abilities on his younger brother’s machine and his own, constantly pushing the limits of his knowledge and craftsmanship.

Through Root River Racing, Jon met Leon Spinden III, and their friendship and shared knowledge led Jon to contribute his expertise to 4130 Motorsport, a national-level team.

We hope Jon’s story inspires you to tackle your own projects—whether it’s fixing a problem or completing a build. Please share this episode with family, friends, and fellow enthusiasts. Thank you for listening!
