    Primer problems

    I have a js550, rebuilt the whole engine last yr, it fires up when i put a lil fuel in the carb and it will run, but when i try to use the primer to dump fuel in it i get nothing to the carb...does this mean my primer is no good...? Im kinda new at this so any help would be great, thanks

    You should be able to feel the primer moving fuel, as well as possibly hearing it spray. Keep in mind that it may take a dozen or more pumps to get fuel into the primer. Is your hose translucent? If so, you should be able to see the fuel moving in it. If you installed the primer fittings in place of the choke shaft, take the flame arrestor off and watch it spray.
