I bad the same problem with the manifold clamps not quite tight enough. I removed the clamps (no small effort) and then removed the screws and the spacer. Then I took off @ 2.0mm from the spacer. Smaller spacer lets the clamp tighten.
Concerning the ‘dead spot off idle’ ... yes it might have something to do with the RECALL but the recall description is best referred to as a hesitation.
Something I found before is 1 or more loose screws of the 6 screws that connect the lower air box to the carbs. That’ll cause an air leak like the ‘dead spot’ description.
