Because the 120AX
RING
is a powerful, large-displacement, single-cylinder engine, it is essential to
use very substantial engine mounting. Conventional wooden mounting beams should be of rigid
hardwood and of at least 15mm or 5/8-in square section. Use at least 4mm steel screws, such as
Allen type, with locknuts, for bolting the engine to the bearers.
