2013 Husqvarna LTH154. It has a Walbro LMK carb fitted to a Kohler Courage 15HP [597cc SV470-3212, S/N 4304637623 build date 15/2/13].
Fuel is collecting inside the air cleaner housing and dripping on the floor - not a large amount, but concerning nonetheless. (I suspect it may be entering the engine too, diluting the oil.)
I tested the fuel cut-off solenoid and the plunger wasn't springing back up every time so I replaced it. But that hasn't cured the problem.
About an hour or two after shutting down the engine the fuel starts to ooze out of the carb.
I finally tracked down where it is coming from - the venturi on the left side of the intake which leads down to the float bowl.
I'm suspecting the float needle, but when I checked it under a magnifying glass it looked good.
Have any of you guys come across this problem before?
What do you think it might be?
Thanks for reading.
Regards,
Chris
