How to adjust the carburetor on the chainsaw

Before adjusting the chain saw carburetor, make sure that the carburetor is clean. The air filter, fuel filter, and related fuel lines are unobstructed, otherwise it will not help.

Mixed oil ratio: gasoline: engine oil = 25:1 (the engine oil is a two-stroke special engine oil)

Fuel inlet: Fuel from the fuel tank enters the carburetor from here

Negative pressure nozzle: connect the vacuum tube, use the carburetor to suck the fuel in the fuel tank into the carburetor through the suction of the cylinder

T key: represents idle speed, adjust the high and low idle speed of the chain saw

H key: stands for high speed, adjust the number of revolutions of the chain saw (control force)

L key: represents the mixing ratio, adjusts the mixing ratio of fuel and air

Adjustment method:

Step 1: If a failure occurs, please turn the screw backwards, turn the L and H keys clockwise, and then back up 1.5 times

Step 2: Adjust the L key to the highest point in the idle state (without increasing the maximum number of throttles), and then back 1/8 laps

Step 3: Adjust the T key to the best state 2800-3200 rpm (without the throttle does not turn off, the chain will not follow)

The fourth step: the H needle is controlled at 9000-10000 rpm, the number of revolutions cannot be too high, too high, it is easy to pull the cylinder, too low, no strength.
