ADVANTAGES• DON’T HAVE VALVES ONLY
PORTS(MECHANICALLY SIMPLER)
• LIGHTER,LESS COST,EASY TO MAINTAIN
• TWICE POWER B• MORE COMPACT• QUIKER IN ACCELERATION• POWER/WEIGHT RATIO HIGH• UNIFORM TORQUE
DISADVANTAES• RUNS HOTTER• NO DEDICATED LUBRICATION
SYSTEM• POLLUTION/SMOKY• MIXING RATIO OIL/GAS -4
OUNCE PER GALON OF GAS • WASTAGE OF FUEL/AIR(GAS)
