How do I check fitment and avoid common installation problems?

Before installing, compare the OEM part number on your old carburetor or the engine data plate to the listed replacements. Clean surrounding surfaces and use the provided gaskets; if you encounter vacuum, fuel, or throttle linkage mismatches, consult the engine manual or a technician.

• Verify OEM part numbers: 16 853 21-S, 1685321-S, 3285361S, 3285347S, etc.
• Inspect throttle and choke linkages for correct orientation and travel.
