    So the fuel pump cover was deff cracked. Replaced it and now idles really well at low rpm. But new issue came up, I had replaced the impeller, old one looked to be in good condition but still replaced amd cleaned out the intake screen, those were messy. Now I seem to have a leak coming from...

    When it started the stream was pretty weak since it was in a garbage can could of been some propeller wash not letting enough water by the intake. However do have a water pump kit amd impeller coming already today. First thing ordered. New fuel pump kit for gaskets coming as well. Should I...

    Have a j8renm. It had beem sitting for a few years.

    So I hooked it up to the boat, looked clean. Hooked up the fuel amd have it a few pulls. Started up no problem. Tried again the next day and ran it for a bit no problems starting. On the third day at the boat launch couldnt get it to go after several minutes. There is a leak in the fuel...

    15hp johnson problems starting after winter

    It doesnt die at speed. It ran great at high rpm, when in low rpm it would sputter out. I took the carb off amd took it all apart sprayed all the ports etc and after putting it back on no luck. I had my compression numbers wrong, top is 80 bottom is 70. I think I'm to the point of just...

    15hp johnson problems starting after winter

    Well the compression tester is brand new from advanced auto parts. I tested it again, and got 80 on the top and 65 on the bottom this time making sure to do minimum of 5 pulls on each. I'll take the carb off and give it a good cleaning. When it does run, it will die real fast at a low idle...

    Well I think all my tinkering is moot. Checked compression this morning, top plug was at 60ish and the bottom 65.

    The carb should be clean. I rebuilt it last year, unless sitting all winter caused it to foul up. The cam roller looks to be in good shape.

    15hp johnson problems starting after winter

    Its the same one. It was laying on the ground all winter if that makes a difference. Also I forgot to run it dry.

    15hp johnson problems starting after winter

    Last year I started having problems with with it starting. So we went through all the issues. Ended up rebuilding and cleaning the carb, new plugs, rebuilt the fuel pump. Eventually replaced the ignition coil. Took it out no problems starting, but the shift linkage disconnected so it was...

    So started the year and things worked fine. The more I took it out the worse it has become. Sometimes upwards of 50 plus pulls amd it still wont start. It will shudder and then die. Back to more pulling. So far I have put new plugs in, took the carb off amd replaced gaskets and throughly...
