Hi Ted, Bumps has a motor that he has done a complete rebuild on (not sure why he did that but he did, he has been doing his head over this motor for 12 months now) and it has exactly the same symptom, with several carbs tried on it.The ones I have do exactly the same. Put it in start, starts instantly, start to move the throttle down and the poppet closes and the motor will die unless you go straight to the run position and then they go full revs, numerous motors and numerous carbs all with the same symptons. This is why we want to get to the bottom of it, it is a design fault in the cam and has probably sent more powertorque motors to the tip than any other problem with them
