    1986 Johnson 30hp - Vacuum lines and throttle control rod

    Worth a shot. I probably won't be able to do that till mid-Sept, but I'll let you know how it goes. Thanks!

    Not yet, was working on getting it up and running before I took it out. Still working on rewiring the boat. Are you thinking that it might behave differently in the water?

    1986 Johnson 30hp - Vacuum lines and throttle control rod

    Well, I held a piece of paper in front of the throat and saw no spattering at various throttle speeds. I also, on a suggestion from elsewhere, took the fuel pump off, put nuts on the two bolts to help hold the thing together and pumped the bulb. I didn't see any squirts out the hole that's open...

    Sorry about that, just learning. It's 1 1/2 turns out like the book said. I have two dogears - notches - and according to the Seloc and Clymers, I should be right in the middle when I first see the throttle shaft move. Edited: I went out and checked and the butterfly definitely starts to open...

    Good callout, I did make sure it was on. I'm using the one that came in the oem kit, so I'm assuming it's a good one.

    That's a pretty big issue there. I'll have to look at the manuals to see how to check all that.

    1986 Johnson 30hp - Vacuum lines and throttle control rod

    Well, I'm stumped. Clamping off/capping the primer system didn't change anything. It's the same symptoms. Starts up like a champ, revs nicely above mid-point in the throttle, but once the roller goes past the right dogear down into low idle, it dies. About 30 seconds later, I've got a small...

    OKie dokie. I'm not as familiar with priming system - the intake cap is the line going to the intake manifold?

    Would I see the leaking after running the motor? At the moment, I don't see any sign of gas around the primer like a leak.

    I've used OEM for my carb rebuild kit, replacement fuel pump (connector on bottom of assembly was broken). I thought the same (about low idle circuit) and did all the cleaning. Pulled the welch plug, cleaned out the holes and carefully put the new one on with a thin coat of Permatex Aviation...

    1986 Johnson 30hp - Vacuum lines and throttle control rod

    For #2, poked around the internet more, found that I needed to adjust that collar/rod that I have circled so the roller is touching the cam between the dogears. Got it. Then readjust the cam/screw to the left of the carb so that the butterfly is closed between the dogears. The "stop" is the...

    OKie dokie, so those small hoses on that T in the picture look OK as they are?

    1986 Johnson 30hp - Vacuum lines and throttle control rod

    Hi everyone. New to outboards, but not afraid to wrench around, used to race stock cars about 20 years ago around local short tracks and was pretty much my own mechanic. I've got an inherited 1986 Johnson 30hp (J30TELCDM) and I'm trying to chase down why I've got a rough idle at just below...
