160DZ problem
 

hi Dave

i am running a YS 160DZ, it ran perfectly for 50 flight. but it has a died stick yesterday. it quit to suck in fuel when i tried to restart it. when i turn the prop the fuel ran back to fuel tank instead of getting in the engine. i checked fuel lines, fuel tank and filters, but all of them works well. then i loosen the screw two turns, the fuel cld be suck in the engine, but i can't get it start. then i turn the screw back to it old place. i worked well again.

today i have the same sucking problem, it seems i have to adjust the screw every time i start the engine. pls let me know what the problem it is

BTW, it is very very hot this day in my place.

The pump is bad and needs to be changed.
