intake and carb sugistions

It's basically what the cam'stroke/rpm are wanting. They want different at different rpms. Bog-carb or timing at that rpm. Run out of fuel at top-pump.

Mid range problems? combination; start with timing, then see what carg sees, as a signal, from the engine.

The engine always tells the carb what it wonts, unless you force the carb to just bog it.
