310-8 Magnum 10 carb linkage

[D_Mac 8,626]

Can anyone send me a few photos of the choke and throttle linkage off the carb? Was taken apart and can't figure it out.

@D_Mac The cables aren't attached but the linkages are still where they need to be.

cables attached.

Think I got it figured out. Thanks for the help !!

I have to get back to working on my '88 310-8 soon, this thread will help me a lot.  Thanks for posting, gentlemen!

I’m in a similar situation but mine is missing the linkage assembly, anyone know where I can get one?

You can try A-Z. They are listed in the vendor section.

@ D-MAC  often refer to this ,https://www.grainger.com/product/45NA65?gucid=N:N:PS:Paid:GGL:CSM-  super lube in small bottle local H/W store , have it in all my cables , linkage areas , done other things also to enhance / ease cable movement . check out the operational temp range .  no cables dry , pete

Does anyone have an adjustment procedure for this or a Youtube link to one? I noticed today the engine RPMs  on my '86 310-8 seemed low. I checked it with a tach and found it was only 3100 RPM. The long spring on mine also seems to be way too long, so I'm assuming something slipped and is not pulling on the gov. arm properly. Many thinks.

With throttle lever on full and engine running, loosen the throttle cable clamp. Pull/slide the cable back out of the clamp until the RPMs are achieved and then tighten the clamp.

Adjustments can also be made by changing the connection holes for the linkage.

What adjustment is the slot used for ?

[Goldnboy 927]

Would this way be considered backwards?

This is a reply to @wallfish's post about an hour ago...

 

Yep, except that if it's original the 1986 310-8 that @Jim Sheaffer has came with a Kohler 241 engine, different setup than what @Goldnboy is working with.  The procedure for adjusting the maximum RPM on the 1986 is described in section 18 of the parts and service manual for that tractor, with one pretty important correction: the "clockwise/counterclockwise" instructions are backward.  Check out this thread for details (that thread was started a long time ago, before some major changes to the forum, so there's some weird formatting and possibly missing comments there, but you'll get the idea): Kohler K241S Throttle/Governor Adjustments - Engines - RedSquare Wheel Horse Forum

 

@Jim Sheaffer, you might want to start a separate thread, before we get too confused.

@dmac  

note very light  extension springs , on choke / throttle assist , also  perforated  go to spring pull  point , very easy to add to any related screw point , also any  movement point is PENETRATING OIL LUBRICATED , like 3-1 penetrating oil , verify its  enhancement , that spring on throttle plate , first photo , is critical for fast starts , almost delicate in its function , yet makes a big improvement in starts .LOOK AT A FAILURE AS AN OPPORTUNITY , TO INCREMENTIALLY ELIMINATE IT , not a one and done , start / stop , easier / same ? make a change , all my cables , linkage points , slide with total ease . pete

Loosening the throttle cable retainer and sliding the cable back still applies and will increase the RPMs, just not the same set up as the Magnum pictured above.

[Jim Sheaffer 11]

Finding this site, and especially this thread, has been most informative. The first and most important bit of knowledge I've acquired is that my 310-8 is obviously not an '86, as it has an M10 engine. Further research is required. Furthermore, my throttle cable sheath is fully retracted at its attachment point at the bell crank, and the long spring connecting the bell crank to the governor arm is jammed together, as if it were too long. The bell crank needs to be rotated almost it's entire distance and when it is, the spring is not stretched at all. Do I? A. Shorten the spring? B. adjust the governor arm? C. Back up and punt? Correct me if I'm wrong.....to adjust the governor arm, do I loosen the arm clamp and turn the governor shaft counter clockwise until it stops and retighten? You guys are fantastic for your willingness to assist. Thanks again!!!!!

Choke rod is upside down.  The right angle offset lets it tuck in behind the air filter without hitting.

@Rick3478 might  get some , super lube on those movement areas , also noting the holes in the cable mount pull point ? added light extension springs from there to  rectifier mount screws , perforated mounting point , lets the springs always assist to close cable movement , very simple add on to cable movement ease . also like 3/1 penetrating oil inside cable movement . lubrication and spring assisted movement , have that on my  3 kohler engines , just an idea, pete
