Dive into the golden era of karting with this rare 1960 vintage manual, *How to Hop Up Your West Bend*, authored by karting pioneers Fred W. Fisher and G. Neal Williams, and edited by Perry McClure. Published by Go-Power Corporation in Palo Alto, California, this 100-page guide is a must-have for enthusiasts, collectors, and mechanics passionate about two-cycle engines and high-performance modifications.

This dynamometer-tested blueprint empowers you to transform stock West Bend engines—covering models 510, 580, 645, 700, and 750—into race-winning powerhouses. Drawing from real-world track successes, including Go-Power-equipped karts that shattered records at events like the GKCA Regionals and the grueling Tecate 100-miler, the book delivers step-by-step instructions on essential hop-up techniques. Learn how to optimize ports for better flow, polish components for efficiency, install reed valve systems, select the right pistons and carburetors, mix high-octane fuels, fine-tune ignition and gearing, balance engines, and even convert to reverse rotation setups.

Packed with detailed illustrations, horsepower graphs showing progressive modifications (up to a 100%+ gain over stock), and practical tuning tips, it's not just theory—it's proven engineering from the heart of 1960s kart racing. Whether you're restoring a classic Dart Kart, building a competitive "B" Class machine, or simply relishing motorsport history, this book offers reliable, no-guesswork advice to put you in the winner's circle.

Ideal for vintage go-kart aficionados, engine builders, or as a unique gift for gearheads. This original softcover edition captures the raw excitement of early karting, complete with black-and-white photos of legendary drivers and modified engines in action. A timeless piece of Americana engineering—grab it before it's gone!
