Cub Cadet with Kawasaki Engine Runs Rough - How to Fix

Step by Step!

Today we'll be working on a Cub Cadet LTX 1142 KW riding lawn mower that has a Kawasaki FR600V engine.

My customer said when he starts the engine, it runs rough and blows black smoke out of the muffler.

These engines have a very common issue that occur, which is the choke lever on the carburetor gets stuck into the engaged position.

They do not disengage properly when you press the choke knob under the steering wheel to disengage the choke, mostly due to dirt and debris creating resistance around the choke lever.

In the past, I have found that degreasing, washing/cleaning the area with a hose, and lubricating the choke lever, works 9/10 times to solve this issue.

However, in the event that the choke lever still gets stuck, you can remove the choke rod to sand it down and lubricate it internally.

A plastic shaft? WOW!
I remember the days when the shaft was brass.

Great advice here, that is something to check out on any motor running rough.

Great video getting right to the issue without someone giving you a tour of their garage and telling you their life's to replace the fuel filter and pump as well and now runs like new..Thank you!

I currently have an Ariens, John Deere, Cub Cadet and a Craftsman lawn tractor thrown away by a local mower shop all fixed by myself with zero dollars spent other than a service. Lack of maintenance and or running over a stick were the problems. Thanks to people like yourself making videos I'm able to fix equipment and help people get something I stand behind for way less than buying big box store cheaply made junk. Thanks

I know nothing about engine repair, but I find myself intrigued and interested in your explanation on how to repair the engine. 👍🏻

[Tommyr]

Excellent. You, Taryl and Dony73 are my favorite small engine pros. Rock on!

[TexasEx]

Thank you for showing how to access and clean the carburetor. This worked for me. Was just about to give up and take in for repair before I saw this video. Saved me alot of time and money!

[davidruiz]

Amazing Instructor; continuation of watching your videos will teach me how to fix my cub cadet tractor. Again thank you for your teaching. Thanks and God Bless.

Well put together video with the perfect easy fix for the customer likely 99% of the time. Most equipment coming in never has the cooling fins cleared of debris, the engine cover has never been off. Explaining this important issue of keeping the engine clean would also make a good video. Thanks for the steak really enjoyed it, best i ever had son.

Thanks! I was literally looking at new mowers and this fixed mine with the flip of a switch! 🎉

[kivettsdmax]

Thank you! My fr750v is doing the same thing, this video saved me a lot of headaches and is an easy fix I appreciate it!!

Very nice video. I have had several YT3000 and YT4000 Craftsman riding mowers that came from the factory with the choke cables out of adjustment. Simply re-adjusted the cable so the chokes would close on a cold start and not more issues. Problem was not enough choke on a cold start and would cause long crank times. Thanks for the video.

[Turningwrenches]

Excellent video explaining the choke and how it sticks because of the dirt and debris and how to fix it enjoy the videos as always

[MajorGRecording]

I have the same motor on a Husqvarna and have the same problem. I watched the Taryl Fixes All video that you mentioned also. Seems like a common point of failure on the Kawasaki carburetor. I think it's past time for an air filter change on that Cub Cadet. Thanks for the video!

[walterbeaver]

Excellent and complete instructions. Thankyou Sir.

A class act credits others, as you did Taryl.

Thanks so much. I had no idea it would be so simple. Fixed it in no time and finished the yard.

[DisgustedGenXr]

I have been through everything on the surging engine on my mower. I put in a brand new carburetor, new fuel pump, new fuel filter, adjusted the valves, new air filter, new intake manifold gaskets, new carb gaskets gapped the plugs….. going crazy. FR600V 20HP

Thanks, I removed the hood and sprayed cables and link with Krown Rust prevention.
