6. Disassemble the fuel lines from the primer to the carburettor at the
carburettor using a small screwdriver to open the hose clamp. Plug the
line with a 6mm bolt.

using a 4mm Allen key wrench. Seal openings at the cylinder heads with
tape. Remove the hose of the coolant inlet (near the starter ring gear) and
seal the inlet with tape.
