Hello everyone! I have a problem here that I have never seen before. I am running a 12.5 briggs I/C engine that loses power when hot and eventually stalls out. After it stalls out, there is a gurgling sound in the fuel tank for quite some time after the engine stalls. The tank is clean, fuel line is new as well as the filter. :dunno: I almost forgot, the vent hole on the tank cap is also free.
