Noticed my ol'reliable 9.9 was a little "off" today. Runs good and starts easy. Went to check points. Good. Sync is way off. Got all the adjustment out of ramp I can get. Roller is about 1 inch starboard of mark before throttle plate moves. Nothing looks overly worn. Something definitely needs renewing. Thoughts for fix?

Remove carburetor.------Look for missing screw for throttle plate.---Simple inspection and costs you nothing.

Old reliable 1974 9.9? Careful, you might make it "good as new", which was not good at all.

There should be a thick shoulder washer between the cam follower and the carb body. Is that in place?
