Toro Z Master Won't Start, Won't Stay Running, Starts Then Dies, Runs Rough Full Diagnosis & Repair

[@johnrose3169]

I think the degraded o - rings in the carburetor were the issue along with the fuel flow from the fuel filter. Problems like the one this mower displayed are difficult as the mower runs when it is in the shop and then it doesn't when the customer has it. In this case, there could be multiple issues causing the customer's concerns. Also, time - whether its is your time or your customer's time matters in this case. You want to keep your customers happy and returns/call backs to a minimum for both the customer and yourself. Going through everything should keep call backs to a minimum and customers happy. Nice video - Happy New Year!

[@IndRepair]

I agree there for sure! Thank you and Happy New Year!

[@bertganstine8029]

Thanks for the video, nice work!

[@IndRepair]

Thank you for watching and for your comment!

[@IndRepair]

@leonardomigot-yn1ti No idea what you are saying here

[@harryrubright6795]

Don't think it was ever the fuel. Good job and happy New Year!

[@IndRepair]

I am with you there! Thank you and Happy New Year for you also!!

[@jgruber2482]

I believe it was the fuel filter

[@IndRepair]

It definitely had a pretty good restriction to it

[@PaulHigginbothamSr]

The float needle was probably stuck off. Or that tiny gasket around the two jets was probably askew. I don't think any jets were plugged but maybe.

[@IndRepair]

There was a good amount of fuel in the bowl didn't seems that way but could have been. I was thinking probably the one between the carb and the fuel tube was probably leaky strange one

[@paulmonk7820]

Could you use a temp fuel supply to see whether or not fuel was the problem before emptying the tank? Or once you put everything back together and running, see if it'll run off the original gas. 34:05😮

[@IndRepair]

Definitely would have worked to confirm or disprove the issue didn't think for a moment that was the issue or I would have

[@paulmonk7820]

@@IndRepair But u did drain the tank and put fresh gas in.

[@IndRepair]

@@paulmonk7820 Yeah, after seeing the carburetor being so clean it had me questions myself. Don't usually but sometimes we all make decisions with haste

[@outlet6989]

Hi Martin, and a Happy New Year. After I saw how dirty that mower was my first step would be to power wash it. I mounted a paper towel holder to the side of my work bench. When I want clean paper I only have to pull new paper towels accross my work bench. A Mini-Vac is a handy tool to have when working on mowers. Octane test strips are available which will show you the octaine rating of the gas in the mower's tank.

[@IndRepair]

Happy New Year to you also! I very rarely pressure wash first, normally done after the job is complete so I don't work on dripping wet equipment. I do have a large shop vac I use often to clean filthy stuff but mostly just blow everything off with the air nozzle

[@outlet6989]

@@IndRepair Thank you for your reply. After I pressure wash my mower, I use my leaf blower to remove the water. I also use it after I wash my car.

[@IndRepair]

Great way to do it!

[@paulmonk7820]

Would a buffer wheel on a rototool help to clean up the plastic mating surface?😮52:40

[@IndRepair]

Never thought to use something like this but it may work with a stiff nylon brush on a Dremel or similar hmm

[@greggcellitti9443]

Hey thanks for the video. Have a great New YEAR!

[@IndRepair]

Thank you for watching! Happy New Year!!

[@michaelfarris2556]

I believe you did the right thing cleaning the carb and everything. If not it would have been back. Mine is getting a new one this year plus a valve job. Down time sucks when your needing your equipment. This was the best time to do it. Nothing is growing in this cold crappie weather.

[@IndRepair]

That is likely the case and definitely a good time to do it! Happy New Year!

[@michaelfarris2556]

@IndRepair well you got this year started of great.

[@IndRepair]

Going to be a good one got lots of stuff coming up

[@Big_Johns]

I'll tell you what Martin that engine configuration is for the birds. Using pliers to start the bowl screws out on this style is always a plus. All that trouble to get the carb off and it's spotless.... very disheartening for sure. I dropped that small right side jet at my bench 2 years ago, still haven't found it. You did a good job, nice video bud. 👍

[@IndRepair]

Crazy stuff there! Never liked the sideways design. Those EFI Kohlers are even worse! Darn brass won't even gather on the magnet stick may be lost forever lol. Thank you!

[@Big_Johns]

Anytime and so very true brother.

[@frankie7508]

Definitely not to fuel in my opinion. O-rings Gaskets had to be changed out in the carburetor and I do not like this Nikki style of carburetor at all. I have the same style of kawasaki engine on my gravely and it would not start. Problem was the choke cable not fully opening up the choke. Had to loosen the spring and address the cable. I Believe the customer when it is a commercial customer. As usual Martin, Your thoroughness and completeness to ensure that the repair is done and done correctly. Nice work, which is why I think you're one of the best in the business! Happy New Year to you with safety and prosperity to you and the family. 🎉 👍👍👍 💥

[@IndRepair]

I agree with that for sure. Thank you and Happy New Year to you and your family! I wish the same health and prosperity to you and yours!

[@christophermccomas5292]

Informative video. I am trying to figure out if it was bad gas. An auxiliary tank with fresh fuel straight to the fuel pump would have ruled out fuel and possibly saved on a bunch of parts being changed and saved customer money.

[@IndRepair]

Definitely! Never seen one looked and smelled good (to me) and was a fuel issue but that would have cleared it up quick!

[@gillgetter3004]

That Kawasaki carb is pretty detailed to rebuild. I’ve rebuilt lots of outboard carbs etc. seem much simpler than that. Haven’t done many lawnmower carbs but man those things are dirty.

[@IndRepair]

They sure are! I am no fan of many of the outboard designs either they seem to make it about hard as possible

[@larrygould8246]

Nice troubleshooting video.

[@IndRepair]

Thank you! Happy new year to you!

[@peterwhitaker-i2q]

Notorius for a blown intake gasket

[@IndRepair]

Could have done it for sure!

[@RonElam-c6g]

Nice job Martin. Sometimes you don’t know what fixes things but the only thing that matters is that it works when your done. Happy new year.

[@IndRepair]

I know you are definitely right with this! Happy New Year!

[@Rein_Ciarfella]

I think it was one of the tiny brass jets that was partially clogged. Anyhow, the fresh paint on the floor in the adjacent room is looking great! Are you using regular deck paint or or going with epoxy? Can’t wait to see your space finished as well, buddy! 👍

[@IndRepair]

That could be the case! We are just using an enamel of some sort. I would love to do epoxy but that price tag was very high for the entire front. Just pressure washed the entire front except for the part that was already painted (where we moved everything) It will look great when it is done. I can't wait!

[@Rein_Ciarfella]

@@IndRepair …and the borrowed dehumidifiers are going full blast. 😂👍

[@IndRepair]

@@Rein_Ciarfella Definitely the truth!

[@paulmonk7820]

If the gasket surface is flat with no interference, rub it on sandpaper on a flat surface.😊

[@IndRepair]

Great way to do it

[@paulmonk7820]

Wonder if there's any videos on carb mfg. 😮

[@IndRepair]

It is made by Nikki like most of the complex carburetor designs. Must have forgot to mention this

[@douglasforsythe5853]

Great video as usual! Have a Happy New Year!

[@IndRepair]

Thank you! Happy New Year!

[@arlodewald5378]

So , you do have an air compressor ? Why would you not blow off most of that dirt and other stuff even before removing any parts before starting to take the carburetor off ?

[@IndRepair]

Clean when it is on vs off doesnt help much. Just personal preference which way you do it. If someone can't be careful about not getting something in the intake when removing the repair will not go well anyway

[@watermanone7567]

Nice work, do you heat the solution in your ultra sonic cleaner? Seems like mine removes about all of the debris if the solution is heated. Thanks for a great video.

[@IndRepair]

Thank you! I usually do but it was cool when put in this time. Seemed pretty clean foe the caked on studd but warm or hot would likely have worked better. Appreciate you watching!

[@vinopan5374]

Hello Martin, I was wondering ,when you sprayed carburetor cleaner into the carburetor and it fired up would it make sense to also try squirting the “suspected bad gas” into the carburetor immediately afterwards to see if it also would fire up. This way you would know if gas is bad or not. Just a thought. I enjoy all your videos and learn so much from them. Keep them videos coming! Happy New Year to you!

[@IndRepair]

Would have been a great way to know for sure!! Great tip!!

[@strokermaverick]

I have a 2018 bobcat 52 inch zero turn. 178 hrs. 23 h.p. Kawasaki. While using, suddenly started flooding terribly. Black smoking. Rebuilt carb, it looked great, inside. No, apparent issues. No change. Replaced carb, new. New fuel filter and air filter, still floods. Floods so bad, it barely runs, then shuts off. Can here a buzzing sound, under the seat, with key on. Any suggestions? Greatly, appreciated. If, you will.

[@IndRepair]

Hmm...I would check oil for gas first. If no gas present pinch off the fuel line and see if it will start and run well right before shutting down. If it does we know the fuel pump is overpressurizing the carburetor causing the issue

[@Lovinflyindrones2022]

Did u put OEM CARBURETOR ON IT OR AFTER MARKET??? COULD YOUR CHOKE BE STICKING??? THIS IS A HEAD SCRATCHER

[@Lovinflyindrones2022]

Let us know what u find

[@eddieg7426]

You Forgot the ground wire, And the butterfly shaft is bent in side the carburetor..

[@IndRepair]

Ground wire definitely hooked up not sure what you are saying about the butterfly shaft being bent

[@paulmonk7820]

Does ur wife know ur usin' her dish towels ? 😅 1:07:54

Lol

[@silwan6784]

Good job, thank you. They should put betters carbs. Less plastic.

[@IndRepair]

They sure use a lot of plastic in this style!
