| 2-stroke rickshaws agree to convert to 4 |
| 2007-08-04 |
| The Karachi Taxi and Motor Rickshaw Yellow Cab Owners Association has decided to convert two-stroke rickshaws into four-stroke rickshaws by replacing their engines after an official announcement that two-strokes would be banned because of the pollution they cause. “Right now more than 100,000 rickshaws are running on the roads of Karachi, Hyderabad, Sukkur and Larkana and if the government will ban them, where will these rickshaws go?” said the president of the association Hafiz al Haq Hasanzai. One two-stroke rickshaw costs more than Rs 100,000 and no owner would willingly stop driving it after the ban. Therefore, it has been decided to convert these rickshaws into four-stroke ones instead of discarding them. |

| #1 Mechanic here, two stroke engines are more than twice as strong, and weigh well under half as much any four-stroke of the same horsepower, they are well engineered and last just about as long, forget lawnmower engines, they compare just like a motorcycle to a ferari, not in the same class at all. They have two disadvantages, first you must mix oil with the fuel as hey do not have a conventional oil holding crankcase, second they burn fuel at twice the rate of four-cycles. The whole diference is design, one is built for longevity, the other for as much available power to light weight as practical.(Longevity is sacrificed for power) To convert anything from two-stroke to four-stroke means replacing the entire engine, there's no "Conversion" kit, the designs are radicly different. |
