I don't believe the governor lever will hit the plate until the governor is actually spinning. With the solenoid up and the throttle pushed, the lever will get close but not actually touch the plate. It's been too long since I adjusted mine to remember the exact details but you just have to turn the adjustment screw on the back until the lever arm is about where you want it with the solenoid in the run position. You may be able to get a better adjustment if you reach in with a screw driver and push the lever forward to contact the plate, but again, it's only right with the engine running.
I think the original idea was to adjust it up a tad if it felt like the lever may be getting hung up under the plate when the engine is started and you press into the throttle to get moving. If you adjust it so it contacts the plate just above the nose, then when idleing it shouldn't ever be under the plate.
