Coming from the motobecane world, a MM before TDC measurement is taken with a piston stop tool. with the tool in the sparkplug hole the piston is stopped at tdc with the tool, and then the tool is used to measure the downstroke distance before tdc. once at X.Xmm BTDC the tool and piston travel are locked, and the flywheel is adjusted just until the points open.

its great if you're a tuner i suppose and want to tinker with your timing but a total pain in the ass if you're unfamiliar with keywayless flywheels.

might be different on a balboa though idk
