General description The C1Q-S68 Carburetor is designed for use with various STHIL blower models, including BG45, BG46, BG55, BG65, BG85, SH55, and SH85. It serves as a replacement for Zama carburetors such as C1Q-S68, C1Q-S68G, C1Q-S64, C1Q-S68D, and C1Q-S68E. It is important to compare the C1Q-S55 and C1Q-S68 models carefully to ensure compatibility, as they differ in throttle linkage and fuel lines.
