Hs45 Trimmer. No Fuel In Primer Bulb.
I have a HS45 Trimmer with primer bulb on carby. When I pump bulb I get no fuel into bulb. There is no fuel reaching bulb side of diaphragm below. I have dismantled and cleaned carby and fitted new gasket/diaphragm kit but no difference. Can get started but will not continue to run and dies when throttled.
