Help needed diagnosing carb issue

Hey all,
Havent been on here in a while, but currently have a couple of 250's in the garage and one of them needs some carb work.

First off a little back ground on the bike:
2006 with 1304 miles on it. Owner let it sit outside for a few months and I bought it as a non starting project.

I can get it to start with the choke on, but once the bike warms up (and it takes a little longer than it should) the idle is rough, dips, hangs if you rev it, sometimes it will rev fine, other times it will stumble and not go past 5 or 6k rpm. Also when i took the carbs off, i noticed there was a decent amount of gas in the boots between the carbs and the motor.

So far ive broken the carbs down and cleaned them, replaced the main and pilot jets with fresh 105/35 jets. Idle screws are 2.5 turns out. checked the diaphragms and they look like theyre in good condition.

In any case, I could use some help diagnosing what could possibly be wrong and where to go next.

You need to make sure all fuel circuits are clear with an air compressor.

A.T.G.A.T.T so I may ride another day.

I'm not your mom and I'm not paying for your parts, so do whatever you want with your own bike.
