I have a 20hp Briggs on my Ariens riding mower.started surging so I replaced the carb with an eBay 15$ carb and the problem got worse. Now you can only run the mower on full throttle. And to get rid of the surge it has to be almost fully chocked. There is a sweet spot and once you find it, it will run. Oh yeah, and when you get the mower on you can’t idle it down. It full throttle or nothin. Everything is hooked up correctly. Idk what to do than maybe just buy another carb? It had a Nikki carb on it oem but the one I bought was just some cheap Chinese junk. Model number on the engine is 331777-2372-g5 also I drained the tank and cleaned tank and lines thoroughly befor the install of the new carb.
