(1) rotate the carburetor main jet needle valve clockwise (close) until it touches its stopping point - DO NOT FORCE OR GO BEYOND THE POINT OF TOUCHING as it may damage the tip.
(2) Rotate the needle valve counter-clockwise (open) 1-1/4 to 1-1/2 turns - this should be close enough to start the engine. Start the engine and let it warm up about five minutes.
(3) Rotate the needle valve clockwise (close) slowly until the engine starts to stall for lack of fuel, then rotate the needle valve counter-clockwise (open) slowly until the engine starts to stall from flooding (too much fuel).
(4) Set the needle valve to a midpoint between the two extremes for the best "purr" of the engine. If the engine "sputters" when a load is added, open the needle valve an extra 1/8 turn for a slightly richer mixture.
If the engine starts and you just want to adjust the carburetor, steps (1) and (2) are not necessary.

If your Mantis tiller starts but won't idle, it could be due to several issues. Common causes include a clogged air filter, dirty carburetor, or fuel system problems such as old or contaminated fuel. Additionally, check the idle adjustment screw on the carburetor and ensure that the spark plug is clean and functioning properly. Cleaning or replacing these components may help restore proper idle function.

To adjust the depth on a Sears mini tiller, locate the depth adjustment lever or knob, usually found near the handles or on the rear of the tiller. Turn the lever or knob to raise or lower the tiller tines, which will change the depth of tilling. For shallower tilling, raise the tines; for deeper tilling, lower them. Always ensure the tiller is off and on a stable surface when making adjustments for safety.
The gap between the flywheel and the magneto on a Mantis tiller is typically around 0.010 to 0.012 inches (0.25 to 0.30 mm).

Always refer to the specific owner’s manual for your model for precise specifications and adjustments. Regular maintenance checks can help ensure optimal performance and longevity of the tiller.
