Teching 5 Cylinder Radial Engine 4 Stroke Cam Roller

This is a corrective part for the Teching metal model kit of a 5 cylinder radial engine. The orginal cam roller provides an inlet valve lift on the ignition stroke, which obviously is wrong. This roller goes directly in place of the original part and makes sure the valves lift on the inlet and evacuation strokes, and they stay closed on compression and ignition.

On assembly of the small centre cog, please make sure that the two bumps on one of the sides are aligned with a piston in top dead center.
