Check your float to see how well it floats. Use a bowl & fill with gas. Use a straight pin & float the assembly. Does it float at a level plane? Also use valve lapping compound. It is a tad finer grit for machining. You should set the float turned upside down seated at a level plane, then set the max drop where it doesn’t hit the carb body. Take a piece of hose & attach to the fuel inlet of the carb. Hold the carb upside down & blow slight pressure thru the hose. The weight of the float should seat the needle where no air can be blown out. If leaking use more lapping compound for a better seat. Use a bright light & look inside the seat for the needle. I have run across broken needle tips in the carb seat area. They are hard to get out. Use a little heat to open up the seat & drop the needle out by smacking the carb body against something solid like a 2 x 4 to get it to come out.
Good luck & hope no broken needles are found.
