help on 1975 johnson 9.9 running

[mrpike1973]

hi today i went on the lake the moter never seemed to rev wide open. then i went back started great got about 20 feet it would start and die all the time. i checked the bulb primer it was hard and getting gas to the connector. if i pulled the choke out it seemed to help some but none the less it would run maybe 30 seconds so i had to row 2 miles back the blisters i could show you hee hee. is this a fuel pump or garbage in the carb never had this happen before. fresh gas ran it before for a good hour no problems. new tank and hoses. please help is my moter ruined or could it be fixed

My dumb question is do you have your tank vent open?

[boatfixer]

So it would run 30 seconds and die? pump it up and the same thing?

[mrpike1973]

yes boat vent is open. yes i would try to keep pumping it up even when it started to run then it would die. it pretty much wont start at this point. it will run for maybe 10 seconds and if i touch the throttle high or low it dies. the bulb stays hard and i can hear it pump gas in the carb thanks for the help

[boatfixer]

The carb is more than likely gummed up. Time to pick up a kit and rebuild it.

try a different tank and hose
