On a dyno, put a bush hog mower on it, go plowing, OR,,, do it with the distributor. You can adjust the timing, to where it puts a load or strain on the engine. retarding the timing, or turning the distributor clockwise (on horizonal mounted distributors) a tad at full throttle can help dramaticly. Now, you dont want to go overboard,, listen to it by ear,, have a helper operate the throttle, and turn the distributor until the engine labors slightly, it will sound like a car engine when you drop it into gear,,, if there is a problem, like a bad plug, or the carb settings are incorrect, it will tell you very quickly by misfiring, or it can actually get hot from the carb being to lean,,,, so pay attention to the heat guage. once you have ran it for,, lets say 30 minutes put the timing back to the book specs, or if your ear is good by ear,, and shut it off,, let it sit and cool completely. this is the time to check all your bolt torques, while its warmed up,, check the head, manifold, carb flange bolts and nuts,, they will be loose, heat from the engine cause the parts to expand and contract, and that makes leaks, and in the headgasket, wont crush properly if not retightened. Valve lash adjustments made, valve cover back in place, all the fluids checked and topped off, fire the engine back up. Let it warm up, and then shut it off again, get your compression guage out, and read all the cyl pressures at cranking speed. Hopefully,,, they are all within 5-10psi of each other,, if they are over 10psi,, the rings are still not seated, or your valve lash is out,, so check the lash first, then do the trick with the distributor again,,, but this time,, you want to put the timing to where it lugs just a bit harder than what you did before,, bout 30-45 minutes,, and repeat the process till they are within 5-7psi of each other.
