Features:
V-Twin
- Features a 90° V-Twin configuration that provides a naturally balanced power stroke, significantly reducing engine vibration and noise while delivering smooth, consistent torque.
Horizontal Shaft
- Equipped with a horizontal Power Take-Off (PTO) shaft, the standard orientation for heavy-duty industrial equipment like pressure washers, wood chippers, and side-drive machinery.
Cast Iron Cylinder Liners
- Engineered with heavy-duty cast iron cylinder sleeves, providing a rugged, wear-resistant internal surface that ensures commercial-grade longevity and superior oil control.
Overhead Valves (OHV)
-
The overhead valve (OHV) design optimizes the combustion process for better thermal efficiency, resulting in cooler operating temperatures and improved fuel economy under heavy loads.
Twin Barrel, Float Type Carburetor
-
Utilizes a high-performance dual-barrel float carburetor, specifically designed to deliver a precision-balanced air-fuel mixture to both cylinders for maximum power output.
Fixed Main Jet
- Features a factory-calibrated fixed main jet that maintains an ideal fuel-to-air ratio, ensuring consistent performance without the need for manual tuning or adjustments.
Pulse Type Fuel Pump
-
Includes a vacuum-actuated pulse fuel pump, ensuring a reliable and steady supply of gasoline from the fuel tank to the engine, regardless of the machine's operating angle.
Flywheel Magneto Transistor Type Ignition System
- Equipped with a solid-state transistorized ignition system powered by a flywheel magneto, providing a high-intensity spark for maintenance-free operation and easy starting.
Full Pressure Lubrication System
-
Utilizes an automotive-grade full-pressure lubrication system with a dedicated oil pump that forces oil to critical bearings, ensuring total engine protection during high-hour commercial use.
Spin-On Oil Filter
-
Features a high-efficiency spin-on oil filter, designed for quick and mess-free maintenance while capturing microscopic contaminants to extend the engine’s service life.
Dual Element Air Filter
-
Protected by a dual-element air filtration system, which uses a foam pre-cleaner to trap large debris and a pleated paper filter to block fine dust from entering the intake.
Bendix Type Starter
- Equipped with a Bendix-style electric starter motor, providing positive gear engagement with the flywheel for powerful and dependable engine cranking.
12v-13a Charging Coil w/ Regulator
- Includes a high-output 13-amp charging system and an integrated regulator to maintain battery health and provide consistent power for electric clutches or lights.
75.2 mm Cylinder Bore
- Features a precision-machined 75.2 mm cylinder bore, designed to house the pistons and maintain stable compression within the $675\text{cc}$ displacement.
76 mm Piston Stroke
- Designed with a 76 mm piston stroke, a "long-stroke" configuration that prioritizes high-torque leverage for powering through heavy industrial workloads.
8.1:1 Compression Ratio
- Engineered with an 8.1:1 compression ratio, striking the ideal balance between high power output and the ability to run reliably on standard 87-octane pump gasoline.
2,400 RPM of Torque
- Specially tuned to reach its peak torque output at 2,400 RPM, providing maximum pulling power exactly where the engine works hardest.
Low Tone Muffler
-
Includes a factory-installed low-tone muffler designed to suppress harsh exhaust frequencies, resulting in a quieter and more professional sound profile.
Automatic Compression Release (ACR)
- The automatic compression release mechanism vents internal cylinder pressure during the starting cycle, allowing the engine to turn over effortlessly with less strain on the starter.
Mechanical Governor
-
Features a high-sensitivity mechanical governor that instantly adjusts the throttle to maintain stable RPMs and consistent power delivery as the engine load changes.
Dual Barrel Carburetor with Fuel Shut-Off Solenoid
-
The high-capacity dual-barrel carburetor includes an integrated electronic fuel shut-off solenoid, which prevents "after-fire" by instantly cutting fuel flow at shutdown.
Electronic Spark Ignition System
-
Utilizes a high-energy electronic ignition for precision timing and a hotter spark, resulting in a smoother idle and more efficient fuel combustion.
Dual Cable Controls
- Designed with a dual-cable control bracket, allowing the operator to manage both the throttle and the choke independently for total control over engine speeds.
