Carb linkage to throttle cable how to?
 
Does anyone have a picture of their carbs hooked up to the similar cable I have? Where do you put the return spring? Can you show where it sits with the sticks at 100% and with them in the idel position please? Here are mine for reference. Anything that looks wrong please guide me here lol

Return springs are not used on boat carbs.

hmmm…. When I do hook it up and put the stick at 100% throttle it doesn’t return the linkage to idle…..

Or you can just use stud with the red morse end that you have. Parts 17-22 https://www.mercruiserparts.com/bam/.../31319/5126/70

87CigCafe 02-27-2023 09:34 PM

Done!

I just received all of these parts today from BAMmarine hooked it all up and it was a fail lol.

87CigCafe 02-27-2023 10:26 PM

?
 
When I hook it all up ( exactly like it was before even using the old throttle cable Mount plates ) it will push it 100% throttle but when I pull the throttle lever at the hell back to idel it will not return it at the carb…..

Are the cables wore out/stretched? I have seen worn cables do this. I also like to put some preload on the cable in the closed position...stick all the way back carb at idle adjust it so the cable has about 1/4 to 1/2 a hole preload as in you have to pull the cable more towards idle position to get it on the carb stud. Hope that makes sense lol

87CigCafe 02-28-2023 07:11 AM

Yep

does make sense yes sir I don’t believe they are worn or stretched but could be! Hard to say yet! Gonna investigate more tbis afternoon!

Pull the pin in the anchor and slide the anchor back...

Adjust the cable so its correct for idle first
You also have some cable adjustment at the throttle lever to play with

I noticed today while fighting this obstacle that with the cables completely unhooked from carbs and plates I get little to zero movement at the cable ends with the throttle levers either at 100% throttle or idel/zero throttle…. Bad cables? Or am I missing something right in front of me?

compedgemarine 02-28-2023 08:38 PM

first. what throttle control is this? some have several attachment points that change the throw of the cable.
second, in the 2nd photo above where is the throttle lever at? the cable is nearly fully retracted in the pic.

87CigCafe 02-28-2023 09:13 PM

Unsure

unsure of brand of controls unfortunately.

the second photo is after a failed attempt at hooking this up and went full throttle with the controls( didn’t really do anything either ) Went back to idel( on the controls) they did not return to full extend for idel position and either.

post a pic of the throttles when you can. on many of them you can move the cable end to one of three positions to make the throw longer or shorter based on the carb and where on the carb the cable is attached. a lot of people set them up at idle but I have always set the wide open position first and let the idle sit slightly up from all the way back. the reason being is I tend to hit the WOT harder and I let the throttle box become the stop rather than the carb as it is hard on the throttle shaft. I dont ever pull back to idle hard so I can control that better and not force the throttle shaft but still have a little extra pull on the cable to make sure it is all the way at idle. just my way of doing it but that was from setting up race boats and in rough water you tend to stab WOT pretty hard at times.

Only picture I have

only picture I have is this one on the gear side if it can tell you much of anything….

looks like an old kiekhaefer aeromarine unit. if I remember right there should be three locations on the throttle lever that move the cable end closer or farther from the arm to increase or decrease the cable throw. you have to take it apart to change it. from idle to wot the cable should move around 3 inches or so. how much does it move now?

Note taken.

just moving the controls forward or back right now unhooked from carb very little if any was getting a bit of a throw at first when I started fooling with this but now basically getting zero. Port side ( unhooked from carb ) has zero just from me looking from the helm over into engine bay

compedgemarine 02-28-2023 10:10 PM

even on the shortest throw it would have two or more inches of travel. you need to pull the throttle box out and see if the cable ends failed or something is broken inside. I have broken throttle levers before and also the cable ends so yes it does happen.

87CigCafe 02-28-2023 10:16 PM

Right

kinda my next thoughts to see the boat has been sitting dead since around 2017 in Florida just kinda chasing gremlins as a I go I seems lol. For Just in case purposes I ordered new cables but if I get around to the boat tomorrow I’ll pull the box and see what it looks like…. Fingers crossed lol

Griff 03-01-2023 12:11 AM

Look at these pics on ebay. You can see the three holes in the levers. Whichever hole the cable is in controls the amount throw

why don't these cables work,is this boat new to you?

87CigCafe 03-01-2023 07:43 AM

Yes

new to me yes just put new engines in her and fixing all of its issues haven’t really figured out why they don’t work yet.

sutphen 30 03-01-2023 07:51 AM

ok,fair enough,,so,your gonna have to pull the throttle up and move the end of the cables so it has the largest travel.plus carb end of the cable can be screwed in and out to further adjust.

87CigCafe 03-02-2023 08:44 AM

Well I’m an idiot.
 
Guys first I want to thank you for trying to help me best you could. Secondly I want to apologize for being a dummy… I have gotten a little ahead of myself and excited about this boat and getting it going and forget to check the obvious. That being said the cables had come undone at the helm. I reset them and all is fine now lol. I apologize.

BBYSTWY 03-02-2023 09:42 AM

Glad you got it sorted out!

87CigCafe 03-02-2023 09:47 AM
