Please note: Because this is a universal fitment engine, certain adjustments to the mower may be required. The engine does not come with an exhaust muffler or a fuel tank. A new exhaust must be fabricated by an automotive exhaust specialist. We do not sell exhaust system for it. You will also need to thread tap the mounting bolt holes at M10 x 1.5.
This engine also requires a separate choke/throttle cable. A combined choke/throttle cable will not suit. Please take the appropriate action.
