What can I lubricate the slides with? That would make sense if they aren't opening with low pressure but when you give it heavy throttle its able to lift.
Needles are straight.

Yeah they are, the most confusing part is that putting someone else carbs in made it run fine and replacing all the replaceable parts in mine with his did not make it run good.
