I doubt it has 4-lobe distributor. Most likely an 8-lobe, dual point distributor as described by toymanbob.

Back in the day dual point breaker plates were available and installed to enhance ignition output and lessen point wear. My guess is one of these after market dual point breaker plates has been installed sometime in the past. Each point set is set to a normal gap of .016" or thereabouts and the timing checked in the usual manner using No. 1 cylinder.

A 4-lobe distributor - dual coil ignition system would be something very unusual on a junior 120. Let us know how this turns out.
