Hi there I ran out of fuel the other day and I am having trouble bleeding the air out of the lines. I have searched the forum and thought its easier to ask, I know this has been asked before so sorry for bringing it up again. Primer bulb is hard, I can get it to fire but it blows a puff of black smoke then stalls after 1 second. I thought I located the bleeder knob (assuming its the little nut type knob where the fuel line coming out of the filter is) When I loosen it nothing seems to happen So i took the fuel line off that comes off this bleeder knob (again I only assume this is the knob) and when I pump the bulb I then get air noise coming through the fuel line. Put the smaller fuel line back on, done up the nut, pump the fuel bulb and its hard again. I had this happen once before and I bled it at the injector but buggered the injector up (cross threaded) so I am hesitant to bleed from there. WHen I take the nut off what I assume is the bleeder knob, there is a little pin in the center, could this be stuck in which is disabling fuel to bleed out the other side? Thanks for any assistance.
 
you mentioned a nut on the bleeder on the injector pump , newer machines were automatic bleeders and there is no wheel to open the valve , older machines have a round knob on the valve , the knob gets broken off a lot and maybe thats what you got but don't see it -----you don't have to totally disconnect the injector tubes at the injector to bleed air , 1 full turn of the nut should be more than enough --------------getting back to your problem , is it only hard starting after it sets up over night or longer , or s it every time you kill it then try to restart
 
On top of the fuel filter housing there is a small, flat-head screw. It may be bronze colored, I forget off hand. Anyway, unscrew the screw a bit, there is no reason to take the screw completely off. Because there is a small hole in the screw to bleed the air. Once the screw is opened up a bit, pump the primer bulb until fuel starts coming out of the hole in the screw. There will be some air bubbles coming at first, but keep priming until the fuel comes out in a stream. Then screw the screw down and try to start. I have always been able to start a machine that has run out of fuel without messing around with the round bleeder or cracking injectors. You may need to repeat the process a couple of times, or it may go on the first try. It helps if someone else is around to keep priming the bulb as you crank the engine over. What you are encountering is not out of the ordinary. Good luck.

thanks for the replies, I didnt try the bleeder on the filter I will give that a go after the xmas break. Had tried having someone pump the primer while turning it over and it didnt work, but I guess it wouldnt if the filter was full of air! Enjoy your xmas.
