walbro wy carb

I have a green machine trimmer with a walbro wy50 carb and put new gaskets and cleaned carb. the engine will run if i put a little gas in the carb but will not start from pumping the primer. I took the carb back apart and can sqirt gas both ways through the little check valve under the metering lever. I think it is messed up. I thought it was only supposed to flow out to the nozzle. Is there any where to buy just the check valve for this? Thanks for your help.

Did you replace the diaphragm? most times I have fuel issues replacing that does the trick. Otherwise you may have to remove the needles and clean them out.
