Possible tune up needed on a Johnson 33?

[catbones]

I thought I would split this between posts, rather then have everything in one.

I've got a 1969 Johnson 33; model 33EL69 .... it's little rough running and shakes a lot (not sure if thats normal), it also stalls a lot in the lowest setting in forward gear or reverse gear... I'm thinking it will need tune up but I'm not sure where to start.

I require help doing it, if anyone is willing. :joyous:

It is supposed to shake back and forth in the rubber mounts. If it otherwise starts and runs ok, I'd suggest tweaking the slow speed mixture one way or the other a bit to see if it will eliminate the stalling at idle. Or maybe you are expecting it to run slower than it can (??)

 

[catbones]

maybe... I just know that I got about an inch left to hit the controller casing and if I do pull it to that one inch zone ... It runs and stops.

You might be right. I donno, just doesn't make sense that I can push it to the fast position all the way and the thing goes, but pulling it back into slow all the way would let it choke and die.

I noticed that if I'm in that low, any turn this way or that way will also try to stall it. Maybe, maybe I just have to adjust something on the control cable so that it doesn't leave about an inch in the slow position for me to go into

Oh well now we are talking about the remote control throttle lever ?? If so, you need to disconnect the control cables and adjust the motor for a good idle in gear. remember the plastic idle speed screw on the throttle gear. Then connect the cables and adjust the control to the motor. Don't forget the idle stop knob on the front of the control. It limits how far back you can pull the lever.

FR thanks so much for all this info I really appreciate it and I do apologize for being confusing in terms and parts.

The motor sounds great in neutral. I guess I've got some listening and figuring out to do with the motor when in gear forward and reverse so it sounds good.

I'll try to take a photo or video even to show what's happening if I can replicate it without dropping it in the water, however I'll do my best to disconnect the control cables, adjust the motor and then see what I can do with adjusting how far my controls go.

There's also a throttle knob on the back of the fast/reverse controller? What that do?

Sorry for being so novice in this stuff

BTW, is it the cables that make the motor so hard to shift into gear (reverse, neutral or forward) or is it the gears themselves? Maybe it's normal for how hard it sort of shifts, I just thought it should be a little smoother.

If the shift lever moves easily with the remote cables disconnected, then it's most likely the cable itself. They get old and stiff and need replacing after 40+ years.

Makes sense, but I believe I fixed it. I had the cables in a loop by the battery rather then giving that loop above the splashwell, just wanted to have it more cleaner. It shifts and stuff much easier.

Thanks for the advice though, appreciate it.

Going back to tune up.

1.) The little thing with a spring on it, where the throttle cable attaches, well that is sure plastic and it was broken to begin with.... any ideas if there's a replacement way to fix this or do I really need it.

2.) I'm attaching a video and you guys let me know if she's running good. When starting it, and leaving it in that position .... it has this clunk that I didn't hear before putting her in the water that I do now, is that a spark plug misfiring ? engaging it to slower or faster throttle stops it... but just half way, she does that clunk. Suggestions?

 

[lindy46]

Not sure what spring you're referring to in question #1.
That "clunk" is a lean sneeze - open the slow speed needle about 1/8 of a turn and see what happens. Other than that, engine sounds good. You may want to adjust the idle up a little bit at the motor. FR describes the procedure in post #4.

Hey guys, btw, I found the issue to my motor not shutting down.... I decided to take apart the part where the previous owner connected the two cable harnesses; since one is original from the engine and the other isn't.

Anyways, taking it apart I noticed that one of the black cables on the harness coming from the switch with more wires then it needed (since it wasn't original) .... that black wire didn't go to no where, it was just taped up. Would never know about it since the whole thing was taped until you untape.. Anyways, remember that wondering light brown wire... at the ignition switch, that was the other black wire. Previous owner connected one black wire to black and the other black to light brown. Who knew... good I didn't connect the light brown to anything positive or would of fried stuff.

Anyways, took it all apart, and will make my own harness out of what I got, make sure I label any wire properly if I don't have the same wire color. Make this thing damn right this time. From testing, touching the two black wires that I cut off from the light brown and one black, the engine shut off just fine.

I'll keep on the progress.
