hi have a homelite 2020 snipper that worked fine and then started with problems, It seems that it will not prime ie suck the fuel through when you pump the bulb, i have checked that the lines in the tank a connected which they are.
so when you push down bubbles come out in the fuel tank, then when you let let go you hear a sucking sound "air" bu t no fuel comes through to the primer bulb??

any ideas thanks jms
