I agree with Nigel, a badly scored crank would not rob you of power, it would loose oil pressure when hot especially, and start to knock when it got really bad, but it wouldn't kill the power.

As you say that it was running OK at idle, it most defiantly points to either not enough fuel getting there when needed, or the ignition timing has altered.

To check the fuel, see just what pressure is being delivered to the carbs, against what should be there. if that's OK, then check the rubber connections between the carbs and the cylinder head, and the manifold gasket.

If it was running OK on idle, because air leaks at the gaskets or rubber joints would make it lumpy, then I'd personally go for the ignition timing going out.
