Since the space between the cylinder, engine block and frame is very tight, the following must be observed during assembly:
The cylinder bolts must be removed. The M5x12 screws to be used are included.
The "swiing" text on the intake manifold must be facing up because the manifold flange has a slight angle.
The milled surface of the air filter housing must point downwards.
Connecting piece, carburettor and air filter must be pre-assembled. Only then does it fit.
