    whats it doing at 3000rpm

    losing power getting none dying
    flat spots, jerkin around, back firing

    check ur timing, points, spark plugs and leads, coil, ballast resistor.
    check ur carbi too could be blocked shit got sucked into it
    check ur float needle and seat in the carbi to and fuel pump could not be getting enof fuel to it,

    lots of reasons why

    hope this helps
