Avs 4425s vs 4615sa

My GTS 340 came with the 4425S and I'm having problems getting to run right. Not sure what the problem is. After I rebuilt it the car will start but if I punch the throttle it bogs and would die if I don't let up and feather the throttle up. I plan on rebuilding it again.

In the mean time I found a 4615SA that the guy who's selling it says is rebuilt to handle the current pump gas and also says it will run on my GTS. This carburetor is listed for the 69 RR 383 standard.

Anybody have an opinion on whether or not this carburetor will run okay or not?

Thanks.
