Now it dies when I give it gas over 2K rpm, it just stalls right out.

Has it been sitting for awhile? Mine was dying out when I pulled the throttle hard, I could slowly pull it and it rev up slow just fine.

What I did was pour some fuel injector cleaner in the tank and went through some gas and it cleared up.

It did sit for a while. I poured a decent amount of seafoam in the tank with a couple gallons of gas. It starts right up and I let it idle for about 10 minutes to help move the seafoam through the system. Even trying to ease on the gas it bogs and stall. The only thing I can think of is there must be a vacuum line I am missing somehwere. The carb is super clean as are the jets. The fuel filters are all new as is the float needles. I didn't take the carbs apart from each other so I wouldn't have to sync them. I also looked in the carbs and as soon as I open the throttle slowly they move in sync. If I just barely open it to where I can slide a piece of paper between the carb and butterfly its the same on the other carb, just barely fits the paper on both carbs.
