Acceleration stutter after service

[dBfazer600]

A quick question before I need to run out of the house.

Took cabs of bike and the pics show what I have found. I do not think they are that bad but there are some concerns and need a little advice.

Pic 7 The filter in the centre of the cabs was not connected to any thing on the bike. Is this correct?
Pic 8 Second in from left screw and washer missing from chock rod. Will this be of detriment on its operation?
Pic 9 Float bowl drain screws. I can not get any of them to move. Do I need them in working order when back on bike and priming fuel?
Pic 12 Ordered new O rings as you can see with the clean gasket and dirty. I is normal ware and to be expected?
Pic 13 Diaphragm housing on carb 2 is sooted up which was not present on the first card. This sits beside the filter in pic 7. Is this normal?

How do you remove the needle from the diaphragm?

Will be stripping the other two carbs when I get back home

Thanks

Daz
