Throttle Question

[AutoAndy]

Trying to sort out the slight hesitancy when running at very low revs (ie poodling along in first gear)....not that I go that slow very often...

One simple thing checked was for any slack in the linkage system. It seems that the first linkage moves a little before the second kicks in (as shown in the photo)but I am not sure if this is an issue or not. The bearing that slides in the linkage is metal and not worn, but it does seem a loose fit in the slot...

...Dear BBC am I paranoid, or is it a sign of something more sinister?

...buT in each case, the slot is still bigger than the bit that slide in it...therefore it does not move immediately that the slotted bit does...ie lag...is this not an issue?
