Installation, Setup, and Maintenance Tips

Replacing seals and carburetor components requires care and precision. Before starting work, ensure you have the correct catalog number 18-7077 to avoid errors. During disassembly, pay attention to the condition of nozzles and needles; if worn, consider replacing them as part of the same service. Remember to thoroughly clean all fuel passages from deposits before assembly to prevent clogging of new seals. After reassembling the carburetor, check the idle setting to ensure smooth engine operation at idle. Regular maintenance prevents failures in difficult water conditions.
