Our RETROL G16 User Guide includes a quick CDI spark test video: if you see a spark, you only need the Hall sensor; if not, choose the CDI igniter assembly. FAQ How do I fit the welded steel gear upgrade? The set replaces the side drive rod, gear and bearings as one unit. After fitting, adjust the gear clearance with the two adjusting screws so the gears turn freely with only a little play. Our G16 User Guide shows both steps with photos. Does my G16 already have the steel gear? Look at the gear on the side drive rod next to the crankshaft. A steel-colored gear welded to the rod means you already have the upgrade. A brass (gold-colored) gear means this upgrade will fit your engine. Can I order a part that isn't listed?
