### ⭐⭐ why wont gas flow into the float bowl is there a tool needed to release the float
*by C***. on August 28, 2024*

great looking carb but did not work ,float stuck ,however the company is sending a replacement out quickly. I hope the replacement is in the proper working condition because the R+R of the carb in the hot sun is not worth doing too many times.why wont the float allow gas to flow into the bowl
