There is no gain just headaches putting a motorcycle carb on a lawnmower engine.

Where though?
Those aren't exactly easy to find it seems(some don't want to let them go).

Is there a good aftermarket clone of them out there?

37.3 second of search time on Amazon:


https://www.amazon.com/KIPA-Carburetor-Briggs-Stratton-10-32XL/dp/B0787WF2FC/ref=sr_1_18?dchild=1&keywords=walbro+56+carburator&qid=1634080806&sr=8-18


It isn't EXACTLY a Walbro 56...


Head over to EC Carbs buy:

Velocity stack: https://www.eccarburetors.com/EC-WalbroBriggs-LMT-Carburetor-Velocity-Stack_p_418.html

Adjustable needle: https://www.eccarburetors.com/EC-Adjustable-Needle-for-Briggs-LMT-Walbro-Carburetors_p_1628.html

You might need a few other parts from EC (or your local Lawn Mower shop if you know how to direct them to look things up)

Now all you have to do is get out the dremel tools and get to work, I'm sure there are lots of threads here to let you know where to cut, where to vent. ETC.
