BREAKing-IN

Note: Since the piston of this engine is not equipped with a ring but is machined to move tightly in the cylinder liner (type ABC - Aluminium piston - Brass sleeve - Chrome plated/Aluminium piston in chrome-plated brass sleeve), you will feel considerable resistance when turning the engine. This is normal. Once the engine has warmed up to operating temperature and is properly broken-in, this resistance will decrease and the correct backlash for operation will be achieved. Under no circumstances should you attempt to disassemble the engine or modify the friction surfaces of the piston in any way. This will only void the warranty. Simply follow the break-in procedure described below.
