Jeff,
Backing off the gov. springs is not that difficult. Take out your torque plate. As you rotate the crank, you will see the adjustment "nut" come into view (there are two of them). I used a dandelion puller after grinding it a bit. There is a slot in the nut that the prongs of the puller will fit into. The stud in the middle of the nut should protrude above the nut equally for both nuts.
Backing off the gov. springs helped my surging problem at low throttle. Is that the same thing you are experiencing?
