Carb came, it is genuine Walbro (has the logo and part numbers and Briggs stamp on it) and is made in Mexico not China. Threw it on as well as new intake o rings. Still runs like garbage and falls on its face anytime you pull it wide open and only getting up to 2200 Rpm and that’s with my finger holding the throttle wide open the governor never pulls it back. adjusted the valves again and still no luck. So at this point it still runs like garbage after a new gapped spark plug, valves adjusted, I’ve tried 4 different carbs adjusted the coil gap, new intake o rings and fuel filter. At this point im just throwing spaghetti at the wall and praying it sticks. I’m going to try a compression test next Or pull the head and see if something is wrong there or with the valves or valve seats.
