    Got no spark now...

    I think I got the float level right on my 1984 Honda Big Red. I put a piece of tubing on the drain and opened it up. The fuel level is right even with the seam in the carburetor. Spark plug is wet now too. Should be close enough to run.

    Now I got no spark.

    I suspect the key switch, and here's why: You gotta wiggle it to get the neutral light to come on, and when I had it running last, I had to wiggle the key to get it to shut OFF.

    There's no voltage to the coil.

    Anybody know how to hot wire a 3-wheeler?

    Can you unplug the switch on the back of the key? If you did this, you would have to use the pull start, but check for spark then.

    Nope, nothing to unplug on the back of the switch.

    I think the connector is somewhere further back.

    From the looks of it, the ignition isn't getting any juice from the switch most of the time. Probably need a new switch.
