Small Engines (Lawn Mowers, etc.): echo gt-2400, gas tank, diaphram


Question
I'm pretty sure I started with a carb problem, I've cleaned it with spray cleaner, then removed everything thats not metal and soaked it, tag wired every opening, and I can still get it sarted, but only when I squirt a little gas oil mix into carb.
Whats got me confused is this, there are three lines running from the gas tank,and I may have them mixed up One connected to the filter,and 2 short ones, one to the second inlet on the carb, the other to a small fuel filter looking thing, But the main thing is I have a new primer bulb but no matter how I run the three lines I can get no fuel into the primer bulb. Thanks my friend for any help.

Answer
Hi Darryl,

The line that goes to the primer is the tank outlet.  The line that goes to the small filter is the vent.  The third, is the return line to the tank.  The carb may need rebuilding, including a new diaphram.

Let me know how you make out.
