11hp horizontal model 252417.

Flojet carb (large 2 piece)

MTD 860

Why in the hell wont the throttle linkage move?

The cable moves free, i got the choke figured out, but now when you move the throttle lever the rod (governor/throttle) doesnt move.

Any ideas? I cant figure this out. Normally i would of just rigged it but i kinda want it to function properly.

Need pix of what you got maybe?  You have a engine manual for one you have?  Should be one on here, covers many models. On most of mine that I have had the throttle cable goes over top of engine, thru a hole in bracket on head, some nuts there or little clamps to hold it in place. The wire connects to that long solid rod, about half-way down. SO, the cable just moves that rod up/down as needed. The rod is connected to arm, maybe gov?? and from that arm TWO springs go over to the throttle arm?  Trying to recall this in memory.  Manuals will show all this. Some link pivots need a shoulder screw to allow it to pivot if I recall. If that spacer or shoulder is gone or fell out from some other time taking apart, the screw will just tighten up the pivot arm and not be good. Positions of those springs is the key to correct action.  Maybe a little soaking on the gov and pivot arms and if stuck, might let loose?   Sorry kinda vague here.  Also the idle and highest speed is adjustable on a rod that goes to top of engine on same bracket mentioned earlier. Couple tiny nuts on it to turn and adjust settings. Many times are corroded and need lube on them to free up. Be very careful turning anything and make sure have pliers holding rod on first few tries, till the threads are cleaned up.

The B&S 2524xx engines used two different linkage set-ups.

 

The engines having date Code # 83121600 (Dec 16, 1983) and before used one style.

 

Engines have date Code # 83121500 (Dec 15, 1983) and later used another style.

 

So sayeth the B&S Repair Manual.

 

I guess that means if your engine was built on the 15th or 16th, you could have either style ????

 

If you can provide the B&S Code number and some good, clear pics of what your linkage looks like, maybe you can get some help.

 

The throttle cable may come in from either direction where it is clamped to the carb.  ...If the movement does not coincide with the push/pull movement of the throttle lever, it may be possible the throttle cable is hooked up on the wrong side.

The rod wont move when you pull the cable when it is off. It should be at wide open throttle untill you start it then the govenor moves the rod. All the throttle cable does is stretch the spring. It doesnt move the rod

Ill get some pics tomorrow. I know the date code dates it to 1977.

I cant find manuals on my phone from this page unfourtantly. Thats why i always ask.

Even if the throttle is suppose to be wide open untill it starts, i think its staying full shut.

Im not sure i got so pissed at it today i didnt really notice much as to what was going on.

Stay tuned for pics.

I second what Tecumseh Power said.  I was thinking it won't move unless running.

Can you start it to see what happens?  

 

Just be ready to shut it down in case it wants to scream.

Ok, heres what i got. After some carb tweaking i got it to run, however, it has no throttle unless you put it clear down on slow, then the governor throws it into full open and it starts screaming. It runs on a low idle from fast to all the way down.

Heres some pics...
