I have a Husqvarna 125B blower and when it sits for a few hours, it floods to the point that I've experienced licquid lock in the cylinder. This happens even when it is stored in the level horizontle position. I cant figure our how that much fuel would find it's way into the cylinder. Once started and warmed up it funs like new. Please help.

The carburetor has an inlet needle that prevents fuel flow when the unit is not in use. There is a certain amount of "pressure" in the fuel system since the fuel cap vents in but is not designed to vent out. The inlet needle will hold off a certain amount of fuel pressure but if it becomes greater than the spring tension that holds it against the seat, it will "pop off" and allow fuel to flow into the carburetor. By the same token there is a diaphragm that opens the inlet needle when the unit is being started and while it is running. The diaphragm works off of atmospheric pressure outside the carburetor to open the needle and allow fuel flow. If the diaphragm becomes "hard" and does not flex back and allow the needle to close, it will also allow fuel to flow and cause a flooding condition. Hope this helps to send you in the right direction.
