One little powerhouse of an engine. At only 35lbs this is one of the lightest singles you'll find anywhere. With 25ft-lbs of torque, this engine packs enough punch to spin up the large props on your backpack parachute, tryke or legal 103 ultralight. Factory recommended TBO is rated at 1000hrs @ 75% power. Standard equipment includes fuel pump, spark plugs, air filter, recoil starter, complete exhaust system and dual CDI ignition for added reliability. When ordered with optional electric start the starter solenoid and voltage rectifier/regulator are included. Standard mounting is plate type from bottom of engine. An optional crankcase allows 4-point mounting (firewall forward style) from the ignition side of the case instead of from the bottom of case. This option must be special ordered and adds 2 pounds to total weight.
