(III. Operating Procedures cont.) 

 

The carburetor has been preset at the factory and probably won't require adjusting. It is 
recommended that any carburetor adjustments or engine adjustments be done by your 

local TANAKA service dealer. If an adjustment is necessary, follow these below 

procedures: 

1.  Start the engine and allow it to warm up for 5 minutes. 

2.  Release the throttle lever and allow it to run at idle speed. 

3.  With the engine idling, turn the idle limiter (I ) clockwise or counterclockwise to 

achieve the maximum engine RPM. Then turn the idle limiter counterclockwise 

one notch. 

(See Fig. 14) 

4.  Next with the engine at wide open throttle turn the "H Screw" (1) clockwise or 

counterclockwise to achieve the maximum engine speed. Then turn the "H 

Screw" counterclockwise 1/4 turn. Now, the H screw should be set between 1 

-1 /4 and 1 -3/4 turned counterclockwise from lightly seated position. (See Fig. 
15) 

5.  Appropriate idle speed is the position where blade does not turn or engine does 

not stall. When the idle speed is too low or too high, adjust it with idle screw 

(2). (See Fig. 15) 

! Lean carburetor settings can cause serious engine damage.
