Re: 9.9 Johnson Carb Question

The throttle cam pick up is adjusted by loosening the two little screws that secure the throttle cam to the mag plate. One screw hole is slotted so the cam can be moved in and out. Some of these screws are pretty tough to get at without removing the flywheel….I would not bend the link rod to make the adjustment, would be pretty tough to get it right.
For now, I would just make sure the throttle is closing completely at idle….I would not be too concerned about the throttle plate starting to open too late…But, the engine surely won’t idle if the throttle plate is not closing completely at idle.
