Yes. Saab, and other car manufacturers with two-stroke engines, had to use it. The two-stroke engine is normally lubricated by the oil mixed into the petrol and when you use engine breaking the engine will not get enough oil for lubrication. > Was > the freewheel removed when the engine changed to 4-stroke? The freewheeling was kept when the two-strokers were converted to four-stroke V4 engines, probably because people liked them as it permitted gear changes without using the clutch. > Your answer > implies that it survived that change for a while. Yes. It even survived into the Saab 99, but only for the 1.7 liter engine during the model years 1969 to 1971 IIRC. The freewheeling was not available for the 1.85 and 2.0 liter engines, probably because the freewheeling clutch did not like high power and rapid activation by clueless drivers. -- G–ran Larsson hoh AT approve DOT se
