How do you adjust a carburetor on a Husqvarna?
Method for Adjusting the Carburetor Start the saw and adjust the L screw by turning it clockwise until the engine almost stops. Turn it counterclockwise until the engine starts running smoothly and then check the adjustment by squeezing the throttle trigger and noting a smooth acceleration of the engine as you do this.
How do you set a Zama carburetor?
How to Adjust a Zama Carburetor
- Set the engine on a hard, flat surface.
- Gently turn the “L” and “H” adjustment screws clockwise until they seat with the flathead screwdriver.
- Start the engine and allow to run for two to three minutes until the engine is at the operating temperature.
Why does my chainsaw stall when I give it gas?
An engine stalls when it’s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it’s idling, adjusting the idle screw, which usually is marked LA, should help.
How do you adjust the high and low on a Husqvarna chainsaw?
- Locate the idle-speed screw and the idle-mixture screws on the side of the chainsaw.
- Turn both the low- and high-speed screws clockwise to the midpoint.
- Adjust the low-idle screw clockwise and counterclockwise respectively, until you find the highest idling speed.
How do you tell if a carburetor is rich or lean?
Typical symptoms of a rich mixture are:
- Poor fuel economy.
- Sluggish acceleration.
- Choke not needed from cold starts.
- Sooty or black spark plugs.
- Sooty or black muffler end pipes.
- Strong smell of gasoline when the machine is at idle.
- Uneven running (will often slow from regular idle rpms and then stop)
How do you adjust a high and low carburetor?
Locate the two fuel-adjustment screws on the side of the carburetor. One will be labeled “Hi” and the other “Lo.” The “Hi” screw regulates the engine at full throttle and the “Lo” regulates the fuel when the engine is idling.
What is the H and L on a carburetor?
They are typically labeled L (low speed jet), H (high speed jet), and I (idler jet).
Which fuel line goes to the primer bulb?
The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. The return line (blue) comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.
Why does my chainsaw start and then stop?
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.
How do I get my chainsaw to idle?
First set the idle speed by setting it as high as possible without engaging the clutch (close to 2700 RPM if you have a tachometer). Then set the low-speed screw by turning it gently in until the engine begins to starve for fuel, then turn it out gently until the engine loads up.
