Model # issues Walbro carburetor

I want to just replace my carburetor for a Briggs and Stratton 12hp, model & type # 282707 012201
And the WALBRO carb only says LMT. There is a list of choices of LMT and I don't know which one to choose. I've seen some replacements named NIKKI also.
I've also seen LMT 5-4993??
Do technicians answer these posts? Ready to purchase.,
