need advice on what could cause this slight engine problem

if it cuts out and then go's....it's lean on the pump shot.

if it bogs then go's....it's too fat/rich on the pump shot.

What carburetor?

Maybe, maybe not. If it's a vacuum secondary Holley or T quad, etc, could be the secondaries are popping open too fast Could be the carb is WAY to big for the engine, and a few other things.

We need more information:

Engine, carb cam, timing, etc. Did it EVER run right, and therefore "just started", or is this a new build or maybe you just changed some things?
