The ubiquitous “shakedown” run is a time-honored tradition carried out by gearheads across the world. The trip could be after completing a frame-off restoration, a long-awaited upgrade, or even just a DIY oil change. The feeling of taking something you wrenched on yourself back on the street or trail is one we all live for.
The primary purpose of a shakedown run is to ensure the repairs and upgrades are enough to get the vehicle ready for the tasks you intend it to do. We’re off-roaders, so a trip into the woods is what we needed.
So it went for our wheeling buddy Justin as he got ready to do a shakedown run in his 1947 CJ-2A. The ramshackle Jeep received only the finest care Justin could offer during commercial breaks—approximately 45 minutes or so. But he’s no dummy—he roped our other friend John into bringing his ex-military 1951 M38 along for the ride. Justin also invited yours truly and my overpowered CJ-7 to tag along. No doubt having access to spare parts and the get-home-alive skills we have honed from years of wrenching on hot garbage in precarious locations were top of mind for Justin.
Our late spring trip took us only a few miles outside of the city of Kelowna to the Thompson Okanagan In British Columbia, Canada. With over 25,000 square miles of public use lands, there are a lot of places to explore. The roof- and windshield-down sunshine was a welcome change from winter. We were lucky enough to have plenty of mud, snow, rocky trails, and dusty forest service roads to test out Justin’s CJ.
It’s not an adventure without a few hiccups to overcome, and we weren’t disappointed. Justin’s CJ2A has a Buick V6 with a Carter carburetor sitting atop an old Offenhauser intake manifold. We had to adjust the carb’s idle mixture screw and float level to get the engine to run properly at high altitude. Then the throttle petal fell apart and we had to reassemble it using some spare bolts Justin had rolling around in the back of the CJ.
Fun times, but we wouldn’t have it any other way. Be it a big project, or just a little wrench turning, the next time you go for a shakedown run, relish in the adventure, setbacks, solutions, and with any luck, victory!
