This covers the following Champion Power Equipment model: 270cc - 389cc Engine Powered Generators, First Generation.
Please note: Read instructions carefully and completely before performing service.
- Remove the gas tank for convenience by taking out the four corner bolts that hold it down. Be sure to turn the fuel valve to the "OFF" position and then remove the fuel line from the valve. Remove the two bolts that hold the frame bar on and slide the fuel tank out of the chassis. Place the fuel tank in a secure location to prevent accidental damage.
- Remove the air filter cover, foam filter, and the four Phillips head bolts securing the grid to the air cleaner case. Remove the two 10mm nuts holding the metal air cleaner base to the engine. Now take away the stabilizer bracket bolt at the lower portion of the air cleaner base. Carefully remove the air cleaner housing and set it aside with all the hardware.
- The throttle spring (fine coiled spring) which is installed around the governor rod can be carefully removed from the black pivot arm on the carburetor. After removal of the springs hook, rotate the black pivot arm in full rotation and lift the governor rod out of the hole.
- At this time, removal of the old carburetor has be done. Pay close attention to the removal of the gaskets and plastic insulator use between the engine and the carburetor.
- Skip steps six and seven if only replacing the carburetor and not repairing it.
- After removal of the carburetor from the engine, hold the carburetor upside down and remove the two Phillips screws that hold the fuel shutoff solenoid; screws may be extremely tight: Please use caution when removing as to not strip the head of the screw. After removing the screws, you can remove the solenoid by pulling it straight away from the bottom of the float bowl. After the solenoid has been separated from the carburetor, remove the thin 14mm bolt where the fuel solenoids fit into. Upon removal of the bolt, remove the float bowl and the float will then be in plain sight. You will find a metal pivot pin at the backside of the float that it hinges onto. Remove the pin and the float will separate.
- Put the new float in place and replace the pivot pin to secure the float. Install the new float bowl o-ring and reassemble the carburetor.
- Reverse the previous disassembly steps to reassemble.
