Chainsaws and weed eaters use the same type of motor: the two-cycle, or two stroke, engine. Unlike a larger engine on a car, these compact engines use fuel and oil mixed together to power a piston and crankshaft.
Herein, is a chainsaw a two stroke engine?
2-Stroke Gas Chainsaw Engine It is called 2-stroke engine because that is the number of strokes or motions of a piston head that it takes for it to produce power. In a 2-stroke engine, the first movement of the piston pushes draws in air and fuel as it moves downwards in its cylinder.
Herein, what kind of gas goes in a chainsaw?
The recommended gasoline in a Husqvaran chainsaw is regular unleaded gasoline. The engine needs a gasoline with an octane rating of 90 or higher for the it to run properly.
To start a 2-stroke engine, you'll need to:
- Turn the stop-switch to the "on" position.
- Pump the primer bulb no more than 4 times.
- Turn the choke on and hold the throttle wide open.
- Pull the cord quickly until the engine "pops"
