Like I said I have a 5 hp briggs that will run fine as long as the fuel tank is full. The thing is when the tank gets below 3/4 it wont take off but will idel.If I put it on half choke it will run to about half tank then wont run @ all.I feel the pick up tube or the pump but not sure. Anyone had simeler problems? Any info regarding this problem will be usefull!
