Things You'll Need
Phillips-head screwdriver set
Tecumseh carburetors are known for their durability and deliverance of raw power for your small engine. Unfortunately, even Tecumseh carburetors need an eventual rebuild or overhaul, and, to work on your small carburetor properly, it must be removed from the engine without damaging the linkages and mounting screws.
Spray each mounting screw, linkage connection and hose clamp with penetrating oil, such as WD-40. Allow the oil to work in loosening these areas for at least 10 minutes.
Loosen all hose clamps. Use needle-nosed pliers and any needed screwdrivers. Twist each hose left and right while gently pulling the hoses away from their connector nipples on the carburetor.
Snap off the choke and/or accelerator control cable knobs from the carburetor linkages and remove the linkages using needle-nosed pliers.
Unscrew all of the mounting screws holding the carburetor onto the engine block. Use a properly sized Phillips head screwdriver.
Install your new carburetor. To do this, work your way backward from Step 4 to Step 1, putting on all items previously taken off.
Use penetrating oil generously to loosen all screws and connectors for ease of disassembly.
Mounting screws holding the carburetor in place may become extremely tight over time. Use a properly sized screwdriver, which is neither too large nor too small for the screw heads. If you strip the screw heads, you may have to take your entire engine to a professional to have the holes drilled out and re-threaded.
