i want to replace the carburetor on the briggs and stratton engine that is on my rotary leaf blower. Its a Briggs & Stratton 800 series engine, model number 126312-0616. I looked on Amazon, but there seems to be numerous types of carburetors for small Briggs&Stratton engines, each a little bit different. Can anyone tell me the model number of the carburetor to buy for this specific engine? thank you in advance.

On e-replacements it shows this one.
