If the problem is due to the vacuum leak what should I try to fix? and How would I be able to do this? If I am not able to fix it on my own I will take her to get it checked out but I would prefer not to do that.
I will make the change tmrw morning to set it at 2k. Hopefully this resolves the issues. If not, anything else is should be aware of?

You are welcome
2K may be a little too high and may difficult the up-shifting:

The petcock is opened by the suction of the engine (vacuum).
The tube that connects both sometimes develops little cracks or pin-holes or just becomes brittle with time, allowing air to come in and partially closing the petcock.
With age, some petcocks let fuel go through even without vacuum application.

Check that hose and also a little filter that goes inside the delivery hose, just before it connects the carbs.
Anything that causes restriction to the flow of fuel into the carbs could make your level in the bowls too low and the mix lean.
