I smelled gas in the barn so, looking at the carb, the outside was wet. It looked like it was coming from around the gas line flange fitting going into the filter screen elbow. I cleaned and rebuilt the carb last year and replaced the elbow, but not the gas line, so a leak around that fitting was not too surprising since I have had to crank it down before. I disconnected the line from the elbow with the shutoff closed. (I always close it when I shut down the engine. It dripped every few seconds. I opened the valve and shut it off and it still dripped. The valve assembly was replaced 2 years ago with a new one from Just8N's. Anyone else seeing this with the new valves?
