Briggs 20hp intek choke o matic not working

[bill.becker@outlook.com]

The choke o matic doesn't work. I have to manually push the choke up to start the engine. What is required to correct the operation of the choke o matic?

Usually it is because the throttle cable has slipped under the clamp just far enough so the tab on the throttle linkage no longer pushes the choke all the way on.
Set the lever in the dash to choke position, loosen the clamp bolt slide the cable till the choke fully engages then tighten the bolt
Do not over do it as there is only about 2 turns of thread to holt the bolt in place.
I regularly end up gluing a nut behind the plate because KING KONG has over tightened the screw .
One of the few places that red loktite is allowed to be used.

Thanks for the help. This is indeed the problem. However, the cable is "weak" and bends a little when in fully throttle position and the choke lever is not pushed up. I'll see if I can adjust it to engage the choke. If not, I'll need a new cable -- but, they're not cheap!

Take the old one to any mower repair shop .
Most will have bulk cable and Z benders.
I charge $ 10 (AUS ) to make a cable.
If your inner is bending and not moving the controls then the coltrols need a touch of lubricant or heaven forbid a clean .

Also can be the choke binding or simply not adjusted to push it close at max throttle. Not always a cable adjustment problem.

Thanks again. I've attached a couple of photos so you can see what I mean by a bend. The cable moves easily to the point where the mechanism, which engages the choke, needs to turn and then it won't go any farther unless I push with my finger on the place where the red arrow is. It takes quite a bit of force with my finger to get the choke to move -- more than what the cable mechanism can provide without bending. Is the cable the wrong one here? The motor definitely won't start unless I push with my finger. Also, looks like this part isn't designed correctly as I don't see how the cable is supposed to make it turn as there is a lot of force required. I tried spraying everything with WD40 and nothing changed. Any help I can get would be greatly appreciated

The choke isn't binding as I can easily push that up with my finger. What is hard to move is where the red arrow is in the photo. Where I push to move the choke isn't shown in these photos. I was told that the engine was brand new when I bought the tractor which is 10 years old. It shows no dirt or anything representing a lot of use

Most Intek 20 hp that i work on is the single cylinder . This is a v-twin so please post the model number and type numbers. Also most these the cable pull to go to full throttle, yours seems operating right the opposite so it needs to mount on the left side and not the right side.

Somewhere there will be an adjuster for the choke lever that has backed off or totally fallen out
Once you get the throttle control to the the position in photo2 it can not go any further which is why the cable bows out.

The engine is a 20hp Intek twin. 40N877-0004. The tractor is an L120 about 10-12 years old. As far as the direction of the cable, I would expect the cable to "Pull" the lever and not "push" it as it currently does. I don't see any way of reversing this.

As far as something falling out, etc. The throttle lever pushes the bracket so far and then the cable begins to bow. I can push the lever further with my finger which then activates the choke and the engine starts fine. However, it takes quite a bit of pressure to push the lever further so I'm wondering what could be wrong as I'm positive that the current cable setup would not activate it correclty

Tomorrow or the next day I'm going to Home Depot which has a whole bunch of John Deee tractors on display and see if they have something similar in terms of the choke mechanism and see if I can determine how those are supposed to work.

Thanks everybody for your help. I hope everybody is staying safe.
