Carburetor 
 

IMPORTANT: To prevent damage to carburetor, have idle 
adjustment performed by an trained professional. Tanaka 
company recommends that you take your unit to your Tanaka 
dealer when these adjustment are necessary. 
 
Model 120 
Carburetor has a fixed high speed jet screw which is preset at 
factory and does not need adjustment. 
 
Model 300 
Carburetor is preset at the factory, however, due to weather 
changes or after extended use it may require idle adjustment. 
 

WARNING: Accurate carburetor adjustment must be made with 
motor running. The propeller will spin during carburetor 
adjustment. Stay clear of propeller at all times and observe all 

safety instructions. 

 

To adjust carburetor, start motor using proper starting procedures, and allow unit to run a few minutes to 
reach operating temperature. Move Twist Throttle Grip handle all the way off, to idle position. Turn IDLE 
adjustment screw clockwise to increase motor speed, counter-clockwise to decrease motor speed. When idle 
speed is properly set, propeller should not rotate and motor will continue to run. 
 
Model 300 incorporates an automatic duel clutch design which allows the propeller to rotate very slowly or 
stop completely when motor is idling. A sub clutch engages at slow speeds and the main clutch engages at 
approximately 6 MPH. 
 
Model 120 utilized a direct drive system. 
 

 

Your authorized Tanaka Dealer is trained and 

equipped to service your unit. A periodic checkup 

by your dealer will help reduce your maintenance 

costs. 
 
If Tanaka 2-cycle oil is not used, we recommend 

stabilization of the fuel with an anti-oxident fuel 

stabilizer, such as Sta-Bil", a product of Gold Eagle 

Co. Follow directions on the product label. 

Otherwise the fuel should be drained before 

storage. Run motor out of fuel as described in 

Operation Section. 
 
Drain gear housing and refill with new lubricant to 

remove moisture and prevent possible corrosion of 

internal parts. To drain, remove propeller and shear 

pin. Remove gear housing cover. Drain grease, 

reinstall cover and refill with grease as described 

under Lubrication and Maintenance. 
Store unit in an upright position on a sturdy stand. 
 
Pull recoil starter rope until a slight resistance is felt 

then slowly release rope. At this point, the piston is 

covering intake an exhaust ports of the chamber. 
 
Clean unit thoroughly. Touch up all areas to 

prevent rust. 
 
Inspect unit for visible signs of wear, breakage or 

damage. Order any parts required and make 

necessary repairs to avoid delays when beginning 

use again. 
 
Cover unit and store it in a dry moisture free area.
