Picture of 149 carb linkage with air cleaner off.

[John TV]

Just put the new to me this year 149 in winter storage. I know that I am not a natural mechanic but I am fairly handy when I do enough research. At this time I’m thinking about spring repairs and upgrades etc.

Currently my throttle will not allow rpm’s to drop past what I believe to be about half throttle. I know previous owners did some carb work but I don’t know if it was done correctly using linkage bits and bobs etc. I don’t remember the manual showing the entire set up as a whole assembly.

Does anyone have a picture of a 149 carb and linkage on the tractor so I can reference and see if I am missing small parts. I will attempt to show what I have now in attached picture.

If I have missed a diagram that shows this, apologies, please point me to the link etc.

Thank you.

That tractor is not a 149, at least the engine is not. It is a Quietline i.e. 1000, 1200, 1250, 1450, or 1650.

Well that is interesting! Guess I’m not totally surprised it’s a Frankenstein tractor. The body looks like a 149 but might have been other items too. Are there any real negatives to this change.

I’m very new to this addiction… lots to learn.

These engine idle at 1680 RPM, I recommend you get yourself a laser tachometer like this and verify before you needlessly start tearing into things.

I’m going to use the excuse that it had been a long day and I have a bad cold… not sure that gets me any sympathy… but I made a rather silly mistake. The picture I posted( I didn’t look close enough) was not from my tractor but rather one I found on the internet to compare to mine… it doesn’t. I looked more closely at the picture and realized I don’t have a dip stick at the top of the motor… Hummmmm senior moment.

My motor looks more like this but I don’t have a pic without the air cleaner.
I do know there are cobbled connections tho and the tractor is now not at my home where I can easily access it to take a new pic.

Good suggestion on the tachometer will look into that soon.
I still would like a pic of the 149 engine without the carb to compare if anyone has that or can point me to a good resource.


Thank you for your responses and please forgive my initial mistake.

Well, that is definetly a 149. It would have had a Kohler K321A engine.
What you have in your picture could be a K241AQS (10 hp), K301AQS (12 hp), K321AQS (14 hp), or a K341AQS (16 hp).
There should be a silver sticker somewhere on the motor to i.d. it.
The big differences between the "A" motor and the AQS motor are:
"A" uses a bolt on starter/generator for starting and battery charging along with an external voltage regulator.
"AQS" has a built in starter for starting and a built in alternator and voltage regulator for charging.
The "A" motor uses an manual PTO clutch for driving implements, the AQS uses an electric clutch.

There are no real negatives to the swap, actually positives, AS LONG AS IT WAS DONE RIGHT.

The major hurdle is that the electrical systems are completely different so major wire work is involved, therefore shoddy work will haunt you.

As far as your throttle linkage, that picture is too tough to make everything out but basically it looks good.

You should go to the Tech Library and download the Wide Frame Chassis Service Manual. Look at the pictures on pages 1-2 and 1-6 for 149 and QL linkages.

Thank you for the link. Looks like it has the diagrams I am looking for.
Appreciate the help. Once I figure out what bits and bobs I need I will try to source from listed suppliers.
