Can anyone help? I have a 2001 johnson 150hp today when iI started it, it ran for a cpl mins and just shut off. during this time it smoked pretty bad, as I was trying and trying to restart it I noticed black sludge coming from exaust after reading a bit on here seems thats normal when gas/oil is not burned off????? also the power pack was replaced 3 months ago. to me it dosnt seem to be getting any gas. I tried spraying starting fluid in it but no luck.it some times will fire up for a sec or 2, also the primer bulb isnt staying hard but not sure if it should if the boats not running??? Can anyone help????? PLEASE!!!!
