Sounds like a power valve problem to me, What rating one are you using?

also make sure it is jetted correctly for your motor.

flat spots can mean the shafts are worn and it is sucking in air through them..

pull the fuel pump from the carby.Is the ball bearing retained by a small metal strip?Are there any holes in the diaphram?Look carefully.Is there 2-3mm free play in the fuel pump plunger?Are the butterfly shafts tight, without wobble? Good places to start.
