When priming a carbureted engine, the pilot’s plan must consider the temperature, the number of cylinders which have priming lines installed, and the number of strokes of the primer needed to produce the correct fuel/air mixture. The primer lines are ordered or installed by the airframe manufa...
The average idle engine speed did increase as the ambient temperature decreased.;The Arctic Cat snowmobile (carbureted two-stroke) was equipped with a choke lever to assist cold-starts. The choke was operated in the same manor for both fuels. Lower le...
If you try to crank the engine and it doesn’t start right away, don’t keep trying. The starter motor can quickly overheat, leading to other problems. Instead, give the starter motor a few seconds and try again. With an older carbureted vehicle, it was easy to use starter fluid to ...
The Electric Choke for Improved Cold Start Control During the warm-up period of a carbureted spark ignition engine, a choke control is required to provide the rich fuel-air mixture necessary to achieve combustion. Over the past decade, a new type of choke control, which uses electrically......
NEDCCombustion characteristicsEmissionThe effect of the liquid fuel in the intake manifold, the ring pack crevices and the oil film on the unburned hydrocarbon (HC) emissions of a spark-ignited, carbureted, air-cooled V-twin engine was studied. Tests were performed for a range of engine load...
