B&S 10/12HP throttle repair

Good morning all,

I'm Jonny, new to the forums and looking for help/advice on a project I'm struggling with.
I have a Husqvarna LT125 ride on mower sat in my garage with a Briggs and Stratton 10 or 12hp engine. The only problem I'm having now is making the throttle work. Engine and electrics are all good, but I simply cannot make the throttle cable and choke system work as its supposed to. The way it is now, is effectively running at maximum revs all the time with the throttle plate on the carburetor fully open.
I don't have the model type and code numbers at time of posting but I will add to the post when I can. There is no cutting deck as it will only be using for towing various things.

It was bought to replace an old one at my cricket club and ideally I would like it to be functional in the next few weeks as we start pre season ground work. I have another question about the other one which I will post separately.

Any information that can help would be much appreciated.

Probably missing a spring or linkage. Will need to find model number for people to give you help. Looks like a Briggs single cylinder possibly starting with 28 on model number (6 digit number).

You are missing both the throttle and choke linkage. Once we get the model, type and code numbers, located on the shroud above the spark plug, we will be able to get you a service manual and part numbers.

His model is 281707-0200-01 with a starting date code of 900214##.

Why not give him the correct IPL?

Because the linkages are the same and I found this one before you posted the model numbers. If the OP would stick to one thread it would be easier to help him and if you would see that there were two threads, you would understand the confusion.

Actually that how I got the engine numbers. But yes one thread is easier to follow. That's why on a forum I manage I combine the threads into one and link one to the other.

So, numbers on the front of this one as best as I can read with 2 digits I can't define
2-2707 015- 01 780417. I have a throttle linkage and spring which doesn't seem to reach the governor arm when the throttle plate is closed, I have no choke linkage. When I bought the mower the throttle cable was directly linked to the throttle plate on top of the carb but it wasn't working. I'm also not sure the governor spring is attached correctly.

I created two different threads because they are different problems on different engines. Neither are currently functional and I'm needing one or both running as soon as possible. I don't know if it makes a difference to parts availability but I'm located in the UK.

So let me get this straight, you created two threads about two engines, with different problems? Are the engines similar? On top of that you didn’t tell us this when you started the second thread. Now you are going to get everyone confused. Can you provide us a picture of the model numbers for the engine you are talking about in this thread. At this time I don’t know which engine you are talking about in this thread. Second, have you opened the manual I posted which contains pictures of how the linkages are attached?

They are both B&S and I think both 12HP but they have different parts.

The engine is this thread is shown in the first post with the red cover. The numbers I posted in the previous reply are on the front of the red cover but are incredibly difficult to make out even up close.

I have saved the manual, it's much appreciated and will definitely be useful.

Take one of your better half’s scrubbies and carefully rub over the engine numbers. Most times this will make the numbers pop out.

Jonny, you say you are new to help forums so I’ve got a couple of suggestions which will help you out. You’ve made some mistakes (posting two threads about different engines, but not clearly identifying what is going on) so I suggest you start over, and follow these steps in both threads.
1. Do not mix any info between threads, each is a separate problem.
2. Post all engine numbers for the engine in that thread.
3. Post your questions as clear as possible, only for that engine.
4. With this info we should be able to help you out.
5. Make sure that you only ask about 1 engine in each post.
Hopefully you will start over using these suggestions, or it is highly unlikely we can help you out.
