    I have a 385777-0349-31 21hp b&s engine that I just installed in place of the kohler on my turf tracer fmd603 s/n 134xxx (don't have anything off the motor). The b&s engine fires right up when starter fluid is sprayed in the carb but nothing other wise.

    Also have some wires that I have no idea what they go to. Any help would be great.

    Let me know if there is any info I need to add

    Don't know about the wiring, but if it fires with starter fluid, it sounds like you have a fuel delivery problem, not a wiring problem.

    You need to put power to the fuel cut-off solenoid and the regulator.....

    The white wire needs power in both the start and run positions.....
