Hello all, My 25cc Homelite Huffy will not suck the tank dry. I don't know what size tank mine is but it's the standard tank that came with the engine. It's an older one ('05) so I'm guessing the tank holds a pint or so. I've gotten it to do better by taking off the filter & putting a one size bigger fuel line on it & making sure the pick up part of it is at the most bottom part of the tank. The engine also has a new Zama carburetor on it so the fuel pump diaphragm should be plenty strong. Still, the engine will start bogging out at around 1/3 to 1/4 of a tank. I start using half choke to refire the engine (then choke off) & then it will run normal as long as it is kept under power. When coming to a stop the engine dies & struggles to start again. When the tank is full to 1/3 or so, no issues. Any thoughts ? ps...Just thought of this. Should the fuel return line be as low as the pick up line ? I'm wondering if once the return line is exposed to air if that somehow affects the situation ?
