Initial setting: Close needle valve (rotate clockwise) until just seated (DO NOT FORCE) and then open (turn counterclockwise) 1-1/4 to 1-1/2 turns. Start engine and let it warm up (about 5 minutes).
Fine tune: After engine has warmed up, slowly close needle valve until engine starts to stall for lack of fuel, then slowly open needle valve until engines starts to stall from flooding. Set the needle valve at midpoint between the two.
If the engine starts to sputter while in service, open needle valve 1/8 to 1/4 turn for a slightly richer mixture.
How do you adjust a float on a Tecumseh carb?
It is usually above the float in the little bowl at the bottom of the carb.

Purchase a rebuild kit. Take the carb off the engine. Disassemble the carb. Clean the parts with carb cleaner. Reassemble and install then adjust carb (if applicable) while running the engine.

To adjust the valve clearance on a 5hp Tecumseh engine, first ensure the engine is off and cool. Remove the valve cover, then rotate the engine to set it at top dead center (TDC) on the compression stroke. Use a feeler gauge to measure the clearance between the rocker arm and the valve stem; it should typically be between 0.004 to 0.006 inches. Adjust the clearance by loosening the lock nut on the rocker arm and turning the adjustment screw until the desired clearance is achieved, then tighten the lock nut and reassemble the valve cover.
