vent tube jet kit question

[first timer]

i was looking at my dyno jet kit trouble shooting book and it tell's me to remove my float bowl vent tubes. Wht do i need to do that for and are they refering to the (2) hoses that connect to the vent t's. The hoses seem like only an extention of the t's and they aren't hurting anything as far as i can tell.

Yes the two "drain" or "overflow' pipes are the ones they are talking about, I dont know why it works , but it does.

Do you have to remove them for normal running, or only troubleshoting?

Does it refer to any particular carb design?

remove them and leave them removed , BTW I only mean the plastic tubing not the T piece.

What problem does this fix? What happens if you leave them on?

As I recall it runns very roughly and has no power , not exactly the result you are after from a jet kit
