Impulse line operates the fuel pump that is usually built into the carburetor. A pulse line is a type of moving assembly line, but it’s one step short of a continuous moving line. In a pulse line, products are positioned sequentially in a straight or U-shaped line on the shop floor.

what does a chainsaw impulse line do Related Question:
What does a pulse line do?
The pulse line connects the pulse chamber. The pressure of the crankcase is pushed by the pulse through a pair on one way valves and fuel passes continuously, and in a correct measure, to power the engine.
Why does my chainsaw stall when cutting?
This is also known as “stalling.” Your chainsaw keeps cutting out or stalls when its engine doesn’t get enough gas and air to keep it working fine. In most cases, this happens because the fuel supply to the engine becomes interrupted.
How do Chainsaw Carburetors work?
The carb is operating “normally” at full throttle. In this case, the throttle plate is parallel to the length of the tube, allowing maximum air to flow through the carb. The air flow creates a nice vacuum in the venturi, and this vacuum draws in a metered amount of fuel through the jet.
How does impulse fuel pump work?
A pulse fuel pump uses the pressure differential produced by the engine to move a diaphragm inside the pump body. This pressure differential is generally transferred via a pulse tube to one side of a flexible diaphragm in the fuel pump.
How do you know if your diaphragm carburetor is bad?
The symptoms of a bad diaphragm are similar to other mower problems. Refusal to start or cutting out during running may be the first sign of a problem. The mower may smoke excessively or sound sluggish.

How does a 2 cycle chainsaw work?
A two-stroke engine, as explained in How Two-stroke Engines Work, has no valves or cams and generates power on every rotation of the crankshaft (twice as often as a four-stroke engine). This feature of the two-stroke engine means that it can generate twice the power of a four-stroke engine of the same displacement.
What does P mean on a fuel pump?
The capacity of both mechanical and electric fuel pump is measured in psi (which stands for pounds per square inch). Usually, this unit is the general measurement for pressure, yet it has slightly different meaning, when talking about fuel pumps.
