    question about primer bulb

    If my primer bulb is bad could I loose RPM's? I am running at 5400' rpm's and 53 mph.. I run a merc EFI 150. I think I should be a little higher on RPM's and top speed

    If your primer bulb is bad you will know it. It will have issues at idle and bog down when accelerating.

    You may be down a cylinder. Check plugs and for fire.
