This carburettor is specific to GGP-manufactured engines. It will not fit models from other manufacturers unless they specifically use this GGP part number.
While these units are often pre-set at the factory, minor tuning of the low or high-speed mixture screws may be necessary depending on your specific altitude and fuel quality.
Use fuel stabilizer in your gasoline and avoid leaving fuel in the machine for more than 30 days during the off-season.
Yes, it is highly recommended to replace all paper or rubber gaskets during the installation to ensure an airtight seal and prevent vacuum leaks.
Cross-reference the part number 1188040070 stamped on your current carburettor or check your machine’s exploded-view parts diagram.
Check that fuel lines are firmly connected and that the fuel filter in the tank is not clogged.
Ensure the throttle cable is properly seated and not binding at the carburettor linkage.
Verify that the bowl gasket is seated correctly and that the drain screw is fully tightened.
Before beginning installation, ensure the machine is powered off and the spark plug wire is disconnected. You will need a basic metric socket set and a flat-head screwdriver. Access the air filter housing, remove the filter element, and unscrew the mounting bolts holding the carburettor in place. Carefully disconnect the fuel lines—be prepared for a small amount of fuel leakage—and attach them to the new unit in the same configuration. Compatibility is strictly limited to models such as the Mountfield MB 33 D, Stiga BC 535, SBC 232, and Alpina ABR/B 32 series. For long-term care, always use fresh, stabilized fuel to prevent the new carburettor from clogging over time.
