ASSEMBLY PLAN Component parts are to some extent fitted together as subassemblies. Mounting the crankshaft bearing Fit the short crankshaft with both bearings in the bearing plate (4). (In case of resistance, you have to support the crankshaft in the middle) Allow the lock washers (4.1) to snap into the grooves on the outside of the bearing plates.

Mounting the cylinder unit Insert the Teflon seal (2.1) into the cylinder housing (2) (can be already fitted inside the housing) Fit the cylinder (3) into the cylinder housing, ascertain that exhaust openings correspond. (sparkplug hole backwards) The cylinder unit is now to be mounted on the cylinder plate.

Sparkplug 2 Sparkplug 1 Ignition View from the flywheel side 20.1 22.2 Timing "Bridge" Sparkplug Mounting the ignition unit. Mount the stator (22) on base plate (M3 x10). Push the cable from ignition through the inclined hole on the stator and guide it into the second hole (A). Push two cables, (red) for the spark plugs, into the short holes on the stator (B).
Mounting the clutch Fit the clutch (50) on the free shaft end and fasten it with M6 x 10 screws. Mounting the carburettor unit Screw in the carburettor pipe (15) with a mounted valve into the cylinder housing and tighten (M10x1) gas-tight, for this, stick a pin or screwdriver through the openings.

Assemble the second engine Proceed logically as explained in 1.1 to 3.4, however, mount the crosshead with valve connection on the left and spark plug hole in the cylinder, and lubrication hole in the cylinder plate forward. Fasten the flywheel (14) on the crankshaft end with M6 thread connection (for CL with the belt pulley)

Putting into operation and tuning 16.1 Check ignition once again Ignition spark must flash approx. 3 degrees prior to the top dead centre of both crankshafts. Corrective measures can be taken for the left cylinder via the position of the rotor (21), and the right cylinder can be adjusted via the clutch (50).
