Features:
V-Twin
- Engineered with a 90° V-Twin architecture, this layout provides a naturally balanced power stroke that virtually eliminates internal vibration while delivering the massive torque required for the most demanding commercial applications.
Horizontal Shaft
- Equipped with a horizontal Power Take-Off (PTO) shaft, making it the ideal choice for heavy-duty equipment like larger pressure washers, trenchers, and specialized industrial machinery where the drive connection is side-mounted.
Cast Iron Cylinder Liners
- Built for maximum commercial longevity, the heavy-duty cast iron cylinder sleeves provide a rugged, wear-resistant surface that ensures stable compression and long-term oil control over thousands of hours of use.
Overhead Valves (OHV)
- The overhead valve (OHV) design optimizes engine respiration by placing the valves directly above the piston, resulting in superior thermal efficiency, reduced fuel consumption, and cooler running temperatures under load.
Twin Barrel, Float Type Carburetor
- Utilizes a high-capacity dual-barrel float carburetor, specifically designed to provide a high-volume, precision-balanced fuel mixture to both cylinders simultaneously for maximum horsepower.
Fixed Main Jet
- Features a factory-calibrated fixed main jet, which ensures the air-fuel ratio remains perfectly tuned for peak performance without the need for manual adjustment or the risk of running too lean.
Pulse Type Fuel Pump
- Includes a vacuum-actuated pulse fuel pump, engineered to provide a consistent and pressurized flow of gasoline from the tank to the engine, even during high-demand operation or when the tank is at a lower elevation.
Flywheel Magneto Transistor Type Ignition System
- Equipped with a solid-state transistorized ignition system, which uses a high-energy flywheel magneto to generate a consistent spark, ensuring maintenance-free operation and rapid starts.
Full Pressure Lubrication System
- Features an automotive-grade full-pressure lubrication system with a high-flow pump that forces oil directly to critical bearings, providing complete protection for the engine's internal components.
Spin-On Oil Filter
- Includes a high-efficiency, spin-on oil filter, allowing for fast and clean oil changes while ensuring microscopic contaminants are removed before they can reach critical engine parts.
H.D. Canister Air Filter
- Protected by a heavy-duty (H.D.) canister-style air filtration system, which utilizes advanced media to capture fine dust and debris, preserving the engine's respiratory health in extreme environments.
Bendix Type Starter
- Utilizes a Bendix-style electric starter motor, providing positive gear engagement with the flywheel for powerful and reliable engine cranking in all weather conditions.
12v-13a or 20a Charging Coil w/ Regulator
- Equipped with a high-output charging system (13-amp or 20-amp) and an integrated regulator to maintain battery health and provide ample power for high-draw electrical accessories and clutches.
80 mm Cylinder Bore
- Features a massive 80 mm cylinder bore, precision-machined to accommodate the high-displacement pistons that drive this engine's impressive $764\text{cc}$ power output.
76 mm Piston Stroke
- Designed with a 76 mm piston stroke, a configuration that provides the mechanical leverage needed to generate exceptional torque at lower engine speeds.
8.1:1 Compression Ratio
- Engineered with an 8.1:1 compression ratio, striking the perfect balance between high thermal efficiency and the ability to run reliably on standard 87-octane pump gasoline.
2,200 RPM of Torque
- Specially tuned to reach its peak torque output at 2,200 RPM, ensuring that the engine provides its maximum pulling power exactly where the workload is heaviest.
Low Tone Muffler
- Includes a factory-installed low-tone muffler, specifically engineered to dampen harsh exhaust frequencies and provide a quieter, more professional sound profile during operation.
Automatic Compression Release (ACR)
- The automatic compression release mechanism instantly vents internal cylinder pressure during the starting cycle, allowing the engine to turn over effortlessly and extending the life of your battery and starter.
Mechanical Governor
- Features a precision mechanical governor that senses load changes instantly, automatically adjusting the throttle to maintain a steady RPM and consistent power delivery.
Dual Barrel Carburetor with Fuel Shut-Off Solenoid
- The high-performance dual-barrel carburetor includes an integrated electronic fuel shut-off solenoid, which instantly stops the flow of fuel at shutdown to prevent "after-fire" or backfiring.
Electronic Spark Ignition System
- Utilizes a high-energy electronic ignition for precision timing and a hotter spark, resulting in a smoother idle, better fuel efficiency, and lower emissions.
Dual Cable Control
- Designed with a dual-cable control bracket, allowing the operator to manage both the throttle and the choke independently for total control over engine start-up and running speeds.
