    1990 Johnson 15hp only start with carb disengaged

    In gear and full throttle, the butterfly is wide open no issues there. My concern is the other direction doesn't have as much range. I found another thread where OptsyEagle mentioned at some point toward slow, the cam roller moves off which isn't my case right now. I will be adjusting the...

    1990 Johnson 15hp only start with carb disengaged

    Okay so I just set the roller to line up center as it touches and looks good now. I've gone through the service manual and the part that it doesn't mention is how much range I should have from full "Slow" to cam/roller lining up. As of now there is zero range. From the picture I posted few...

    1990 Johnson 15hp only start with carb disengaged

    Cam looks just slightly off to the right. Can someone confirm, it SHOULD be lined up dead center when the handle is at the START position and not SLOW? This is as far as I can twist the handle towards slow trying to line up and at START it's even further off being that it's already past the mark.

    1990 Johnson 15hp only start with carb disengaged

    That was a great idea! I finally got to it and it all looks good but the line is far right and it's not close to lined up. Can just line it up by adjusting the linkage or is there a more proper way to do it?

    Is this too much oil for 5 mins? Almost looks like a leak

    1990 Johnson 15hp only start with carb disengaged

    4 turns out is the suggestion from the service manual but I've tried it all, it doesn't affect anything. Seems to be running too rich, spark plugs are wet and today it suddenly only starts with throttle open.

    I think they're close enough to not be a problem.

    1990 Johnson 15hp only start with carb disengaged

    I have the red kill button at the end of the tiller hande so I'm assuming its probably not supposed to die when it's turn fully to the opposite end.

    1990 Johnson 15hp only start with carb disengaged

    I sprayed it down and put it back together, but also the plastic carb body cover was replaced since it was cracked so the idle needle and the cam barrel had to be adjusted. Also while it's running on neutral with tiller twisted towards start, is it supposed to die off when I twist it back the...

    1990 Johnson 15hp only start with carb disengaged

    Model: J15RESR Previous owner couldn't get it to run, I cleaned carb, swapped plugs and wires, and replaced carb body cover which I found was cracked. Only thing left is cam roller missing a rubber sleeve I haven't fixed. Running 50:1 With needle idle set at 4 turns out and choke engaged...
