[30 Closed Cab PU]

When checking for leaks additionally check the inside bottom of the air intake with your finger, sometimes leaks are so slow it evaporates and you do not see it.


As said above no harm in running the bowl dry.


If you want to check for leaks - if the carb leaks with the fuel shutoff off, then the shutoff and the carb float valve may both be leaking. If it leaks from the weep hole in the air intake and does not stop over long time, you have both issues. If it leaks a little and stops, possible it is just the carb, and leaks until the gas line has drained into the carb bowl due to the leak.


How to tell? Turn off the fuel valve, drain the carb by removing the drain bolt, allow to sit for a while so it is completely drained, then put a small container (small jar/soup can/etc.) with a tissue or piece of paper in the bottom and leave overnight. Then check it. If there is gas in the container or the paper/tissue is stained your fuel valve is leaking.


Fix the fuel valve. Then fix the carb if it leaks when the fuel valve is left on overnight.
