noise problems at high rpm

I'd agree, it sounds like it may be fuel starvation since it cuts out sooner in higher gears. You're probably emptying the carburetor fuel bowls at high rpm and need a new fuel filter, bigger fuel pump, or bigger fuel lines.

Tell us about your combo...at least the engine and fuel system.
