Status: offline 		I have an older 120 model ys that just started this problem. I flew today one flight and upon landing I noticed the idle didnt seem right. I shut it off and when I went to fuel it fuel was dripping out the cowl. I took off the cowl and fuel is dripping our the carb barrel and when I run my fuel can pump backwards the fuel that is being drawn out is full of air. I checked the check valve and it is holding good and my fuel filter is clean. I dont recall this ever happening before. Any suggestions?
thanks
Jeff
