    Carb & Tachometer Problem

    I don't know if these 2 problems are related but here goes.
    1. The Tachometer (Rev Counter) on the dashboard stopped working for no apparent reason, what/where should I be checking, and where/how is does the gauge get its reading from the engine?

    2. The following week after the above problem appeared, the engine developed the following symptoms. When pulling out a skier it seems very sluggish, it then picks upand runs okay but when you require extra power to get into 30/32 there is non to be had. Then the engine will deliver the extra power but in an on/off state so it appears that the driver is playing with the throttle.
    Any ideas?

    The boat is a 92SN with 285hp electronic ignition, and a holley carb (2 seasons old) fitted by the dealer.

    Please give any suggestions is basic laymans terms, I am learning but have a long way to go before I am classed as a mecahnic.
    Thanks

    Check The connections on the coil The green wire runs the tach. The loss of power may be a problem with the timing due to the Elec Ign or corrosion on the coil terminals
