am not satisfied with the performance of the product , the gas is not working and also the carburetor head choke not work fine, it removes almost immediately fixed by the technician
Nice dual (tripple) duel carburator for Chonda 168F or 170F engine typically for a 3000W generator. The ornage knob control the NG or LPG gas flow rate. In few sites, info indicates Horizontal direction is for NG, and Vertical for LPG. Knob can be adjusted slightly to get the optimal flow rate. P.S. white platic lever is to drain the petro/gasoline in the carburator cup. Additional info: Natural Gas 0.25 PSI (8 inches of water column), while LPG (after its own regulator) will be 0.4 PSI or 11 inches of water column.
