[@johnhitchings3320]

Thanks so much. You made the task so easy to understand and perform, that I've decided to open up my own mower engine repair shop, and look up your repair videos whenever a mower comes in for repair.😂.

[@803dj5]

man with youtube long as u got a mechanical mind theres so many videos to watch that u can turn into a hustle or full time job

[@Tiredofthecrybabiesonutube]

That’s one hell of an idea lol👍🏼😂😂

[@christophergilbert506]

Bro you don’t know how much you just helped me, I got this same mower last year and just now realized it’s only been running on one cylinder from a bad coil, I’ve been lost in what kit I needed to buy and if it’d even work but here you are saving my day, thanks man really appreciate it

[@imacgst27]

As always you explain everything so well, without all the extra stuff most KZbinrs add. Thank you so much for helping me once again, this isn't the first time and it won't be the last.

[@gregoryarnold9325]

Dony you're the best at what you do and you give great tutorials, you're a blessing to small engine Mechanic's so keep doing what you do and Thanks 👍.

[@philliphall5198]

Thank You for information and advice We’re all learning from you guys in full time businesses who share your experience with Us 😊😊

[@Tyroma]

Just installed this kit today…100% improvement! Not only was my tractor only running at one cylinder, but the other one was weak. This coil update has it running like a new machine again. And this video was a great help, especially with showing what to do with the red wire.

[@mikezyrowski8254]

Nice job thanks. Appears fixing a Koehler design problem. They should cover.

[@Jflowboston1]

I watch every vid you upload, thanks

[@robbeaupre8110]

Same here... completely agree. It's another reason to look forward to Fridays!

[@mmafanatic90]

Seems like the “courage” models of Koehler engines have so many coil issues! Great video, you make it look so easy!

[@JodBronson]

Kohler is just a brand... Newer John Deer, Kohler, Husqvarna, MTD, ETC.... Any of them have the B&S "Twin" Engine Cylinder have the same thing.... It's the *STUPID Engineers, just like the Fuel Solenoid!!!*

[@imacgst27]

@@mmafanatic90 also known for their cracked cases, that mostly all crack in the same spot. Not all do it, but a lot do 🥺

[@trentharris2134]

Thanks! Appreciate the video. Like you said, the instructions that come from Kohler leave out quite a few details.

[@rayaratkon1654]

Hi, Good video and well explained!! I have a Husqvarna Ride on lawn mower with Kohler DSAI engine v twin cylinders It starts well but sometimes the engine won't shut off 🤔 any help will be appreciated. Regards Ray

[@richsmith9063]

Dony, great video Thanks !! I'm very ticked at Kohler ive got a CH740 in a Cub Cadet XT3_GSX & it appears a coil has gone bad after 240 hours. Inexcusable !!!

[@steakdogs]

Thank you! One of the best mower repair videos and made my repair job much easier! The instructions were garbage.

[@johnbundy9223]

Thanks for a awesome video had to replace on my Kohler 27 hp it’s on a Bad Boy ZT 65inch you were right no where in Kohler s instructions do they even mention the hot wire to the fuel solenoid on carb thanks so much for making this so easy runs like a new one 🫵🏻👍!!!

[@V8SKULLS]

Thank you so very much for your time and knowledge and patience, you've made it so simple and easy, God bless down here in south Florida

[@XBOXHOODLUM]

Took several hours but I traced my problem to the 60deg tilt switch. Not sure how this goes bad but it was causing my bizarre cutting in and out problem. Bypassed it and all runs good. My ignition module (PN: 24-584-15) was not listed on the Toro Bulletin so I guess mine are ok. Do you agree?

[@Jim-ie6uf]

Thanks for a great tutorial.

[@bamabluesman]

Thanks, This video helped me a lot. I went a step cheaper and made my own conversion kit with the old wiring harness and some crimp caps that I had in my collection. Another video had same info but yours has a nicer tone. Saved some bucks and fixed it for 36 us Dollars.

[@johnhitchings3320]

I have this same engine and I have replaced all filters, fuel pump and carb. Using a spark detector like yours I have spark. My engine still misfires at high rpms. Any suggestions? Thanks for any help. John H.

[@yaris0069]

Learn a lot watching your video. Saved me some repair cash.

[@wyley87]

I've done this twice on a 72' Toro z500. I ended up removing the engine to do all the work. It's a horizontal shaft, only 4 bolts and belt and a few connections to remove it. That mower recently got a new engine, so I'm sure I'll be doing it again in a few years.

[@billlovett4256]

As always awesome video. Keep on wrenching!

[@foldingchaise8387]

You are very professional keep up the good work, Thanks !!!!!

[@donyboy73]

Thanks, will do!

[@boatbuilder1954]

I have a kohler command ch20s. My coils look just like the ones you removed. Presently It runs good but should I buy a kit just in case or didn’t the ch20 command have this problem? Thanks great video!

[@vetterfellow]

DB73; I'm still learning good stuff on your channel. Splendid video..

[@abern0417]

Saved my mower! It runs so much better now. Thank you!

[@Histandard2011]

Dony, had an engine shop like yours for years. Just a suggestion when replacing coils. Remove old like you did, then install new ones with flywheel magnets out of the way but then just snug up new coils, then rotate the magnet to one coil, place business card in place and then loosen coil hold down bolts. Magnets will pull coil into place, tighten hold down bolts and you are off and running without having to fight the magnetic pull on the new loose coil. Just a suggestion.

[@johnwilliams-ww4kw]

Same problem here brother im gonna buy 2 coils here at my wholesale house and make my own harness. Thx for confirming my idea will work..... Thx

[@donyboy73]

Glad I could help

[@johnwilliams-ww4kw]

Just wrapped it up .. Worked perfectly... $$$$$ payday

[@markhumphrey4834]

Top notch like usual Don,Ive learned so much from you it has enabled me to keep up maint. On 3.5 acres by myself yearound thanks sincerely brother

[@robertmailhos8159]

Great job on the mower my Canadian brother 😀

[@tonyanderson9766]

Great to the point video step by step easy to follow.

[@servihomestead4324]

Flat side up. That's what I was looking for. Thanks, Don!

[@zx8401ztv]

Smashing conversion, it's just like B&S push mowers now. Just omit the power wire from the coil packs basically. Any problem with the timing or is it just an engine that does not care much?

[@paulbillings1791]

Even if it did care much,there is only a few thousandths play on the coil mounting bolts left to right. Engineered to the highest good enough standards.

[@zx8401ztv]

paul billings Ha ha "Engineered to the highest good enough standards." :-D That's a new one to me, nice :-D Sounds much like simple twostroke moped engines, who cares how close the plug and points gaps are, the stator plate is bolted down so it should work. It has to be rotated!! oooow :-D

[@mserrato587]

What coils would you recommend for a 2012 Kohler Command Pro CH750 -3005? Thank you

[@chrisnixon9738]

Hope you can help. I have a single cylinder Kohler pro Model CV16S-43519. It has lost spark and has module 9906 Rev A also a marking 100532 if that helps. Also it has a rectifier/voltage regulator. How can I test which is bad or is there a modification you can recommend? Thanks!

[@marksteve4065]

Your doing this on a Kohler 26hp courage. Will my 24hp courage need the same kit

[@leshall3013]

Hi Donny have you done this on single cylinder kohlers? I have a kohler CV 16 S that has the DSAI module with three prongs, I bought a new coil that is suppose to be for CV 16 or CV 16S but only has two spade connectors and they're not marked like old one. Thanks in advance!

[@transformer889]

I have the same engine as yours, 5 wires come out of SAM, the yellow and brown go to the ignition module, Black to the ignition body, Red and white to the engine side red, and white. All wires are keyed so can not make a mistake

[@trevorcapon8700]

Hey Don. Just installed this Ignition Coil 2 Pcs Replace 32-707-01-s 25-707-03-s 3270701 Fit for Kohler SV735-0017 SV740-0020 SV735-0018 SV735-0019 SV735-0002 SV740-0002 Lawn and Garden Equipment Engines Ignition Coil 2 Pcs Replace 32-707-01-s 25-707-03-s 3270701 Fit for Kohler SV735-0017 SV740-0020 SV735-0018 SV735-0019 SV735-0002 SV740-0002 Lawn and Garden Equipment Engines and the mower is just turning and turning. NO FIRE...Ideas?

[@evelynboshell23]

Is there a similar procedure for a Kohler cv16s single with a SAM unit integrated into the ignition system. A new oem coil did not solve my week spark issue and I cannot find any information on how to test the SAM unit. So I would like to switch to the old fashioned coil if possible.

[@gocart09]

Do you have a video on this style tractor with steering linkage because my camber is way out when I go forward and then it's way when I back up

[@harmonysprogress]

Will the same method apply to my SV7350016?? I found the modules for mine..

[@homermoore29]

I purchased coils off of Amazon. When watching your video on replacement coils, you just have one tab to connect. The ones they sent have two tabs, with no instructions on where or what they are for. The ones that I have are the same number sv740 that it says on my tractor. Can I still use these and if so, can you share with me what wires go where. Its a twenty seven hp twin courage. Your response would be greatly appreciated. Homer

[@GrampiesWorkshop]

How's she goin'? That's an interesting repair. Funny that Kohler has made the change in the coils like this. I guess they know the OE one wasn't up to par!! Thanks for posting.

[@carminesarno9814]

Where can I buy the old style coils for my Koehler 26hp motor. I tried buying them from discount online parts, but they cancelled my order and refunded the money saying that they are out of stock.

[@unclebs4732]

Is it ok to paint the magnets on the flywheel ( keep them from rusting) with a lite coat of clear paint or will it interfere with the current? Thanks for the info and great job!

[@richardcranium5839]

wax or oil works better

[@donyboy73]

do not paint the magnets, u can spray wd-40 or some other lube on them

[@4staroffroad]

So I did the update and for some reason I now keep popping fuses. I can start it up, it runs for 10-15 seconds and the fuse pops. Any ideas on what I should look at to troubleshoot?

[@pl747]

I buy just the coils off ebay for twenty something dollars and all you have to hook up is the kill wire(s). And they fit the single cylinder engines too.

[@togodbetheglory9725]

Hi I have a question...I have a mower Dixie chopper 2017..it won't start. It cranks but no start we checked the both ignition coils there's no spark..I m not to convince bcuz both aren't sparkling. also the ignition key don't work..at cranks only if I do it directly to the starter..any suggestion will be appreciated thanks for your good advices. God bless

[@harrybarc4255]

Great explanation

[@spiceyfrenchtoast9421]

question, I have a Kohler command pro 20hp cv20 engine. it feels underpowered, and after doing some research, it appears that the 18-22hp models all use the same block, just the cv22 uses advanced timing. what would, or what could I do to boost the HP our of the 20hp engine? can I put the carb on from the 747cc 27hp model, or remove the governor and run it at 4000rpm?

[@watermanone7567]

Excellent video Dony: Does Kohler ever warrantee those coils. Kohler seems to have lots of issues these days. Oil leaks on the pan, carb issues, etc. Many thanks for the video's.

[@donyboy73]

I haven't heard of them replacing out of warranty period

[@jpozenel]

I bought a Cub Cadet XT1 a couple of years ago with a Kohler 22 HP engine. It's running great so far. Is this something that I should be worried about?

[@donyboy73]

not really but if it is you'll know what to do

[@deanmoore3776]

Hi Donnie just wanted to let you know awesome video on the Kohler engine coil update I did my first one yesterday it came out pretty good just wanted to thank you you have great videos I watch them all the time

[@JOEZEP54]

Hi Don, It has been awhile. Hope things are going well. Stay in touch. Great video. Stay well, Joe Z

[@transformer889]

Don, what is the part number for single cylinder 16 horsepower Kohler engine, I have Kohler CV16S with the Spark Advance Module, many thanks

[@PatrickKanatzer]

Did the kill wires have diodes inline and if so were they of any concern in your diagnosis?

[@cabbyhubby]

So: Red to gas solenoid: White to coils: and Green to ground , is that correct?

[@gphilipc2031]

Will this (concept) work on an older 20 HP Merc OB? It's a 2 cyl, dual ignition points engine currently? I have seen these engines equipped with under flywheel and some with external coils.

[@AD-nn7vh]

Is that a homelite chainsaw, I have the same one it's as old as I am not many left.

[@ArizonaCowboys]

Thank you for doing this video!! Any chance you have done one of these on a miller trailblazer with a kohler command Ch750 not efi? After mdi conversion my stepper motor starts the engine up but i seem to lose any communication after that and just runs wide open..also does not shut off. I did the wiring right but something is amiss

[@24BLUEELMO]

I just got the same mower . I move the throttle lever up and down but the engine rpm doesn't change. Any tips ?

[@motoman5023]

Thanks for the video i can,t believe i have not done any of theese. And i have seen a ton of theese motors

[@vikingerik80]

Great video DonyBoy73 as always! Do you know if the heads for a Kohler SV735 and KT740 are interchangeable? The SV735 heads are shot and I have almost new KT740s!

[@iwanaGoFast2010]

I had intermitting spark with dsai, i have the same engine a kohler courage sv735. The kit i bought with the same part number your showing on your box and my mower runs like garbage. Both are sparking but its running like its missing or out of time? I'm at a loss i been working on these things for years. Please help.

[@Firby1988]

Any chance of running cdi ignition boxes and add the pickups ware the coils were removed from using the flywheel magnets as the pick ups ?

[@803dj5]

in for the asnwer to a good question

[@kenh9176]

briggs and tecumseh feed the kill wire of each coil through a diode before going to the common kill wire to chassis . What's different about kohler coils that they don't need the diodes.

[@clauslundberg9224]

Super video - real DB73 quality repair. Thanks for sharing

[@waynemeierdirk]

My coils come with 2 wire spade connector ? one is the coil kill ! what is the other spade connector used for

[@stevefleck5892]

Thank you for another great video. I always look forward to getting your notifications...

[@philliphall5198]

Could you show how to test the new style Honda 4 terminal coil with meter for GX 630 ?????

[@elevatorman427]

My neighbor give me last year his 2009 Craftsman YTS4500 with that same engine because it would sometimes hit on both cylinders sometimes not. I just put that same kit in it and runs like new now. I have other issues I need to eventually address on it but, I wanted to make sure I could get it to run on both cylinders before doing much else with it. I have to agree Dony those instructions are very vague.

[@ittech4695]

Couldn't you use the aftermarket ignition coil and create your own pigtail? What is the Guage Wiring?

[@bentullett6068]

Don't have many Kohler engines fitted on machines sold in the UK now. But we are having issues with the new Briggs and Stratton engines fitted with the electronic choke system and choke adjustments as we have had these cut out on customers.

[@wenfordcampbell501]

Do they make a advance modular lgnition coil for a kholer cv25 1997 model or can i take two coils and make my own

Great job, I'm really liking that spark tester you used, can't find a video on your channel about it, where did you get it?.... I wanna pickup 2 of em..... They seem to have a nice large sight window.

[@randomwrenching]

Don got his Blue Point version from a Snap-On guy, but the same spark tester is available from Lisle Tools (P/N 20610). It can be found at many auto parts stores or on Amazon if you don't have a Snap-On guy around. I have the Lisle one, it works very well, I use it all the time. It doesn't work with spark plugs that have the threaded ends though, won't securely attach inside the coil wire boot...

[@randomwrenching]

Companies are constantly coming out with "latest and greatest" designs like those powered coils. Then their designs fail...then the companies revert back to the same old systems that have worked very well for many, many years. (And of course they charge the end user for the retrofit parts). Frustrating...

Clear, well explained video. Well done Dony. Does the coil on the Kohler Courage single-cylinder tend to fail the same way? Is there a kit for that too? Thanks!

[@donyboy73]

yes they do fail on the single cylinders a lot too but usually no special kit required

[@bobmcl2406]

@@donyboy73 ok thanks. Good to know. I have been keeping a Kohler Courage Single alive on my son's Cub Cadet tractor. Certainly not my favourite engine. But your advice is always useful when I go to my local small engine parts shop. It helps me understand the excellent advice that they give me.

@donyboy73 my courage sv725 when I engage pto seems the engine won’t run right when cutting. Almost Bogging down. I’ve cleaned carb, adjusted valves, new plugs. Cleaned Magnito. Could my could be going bad?
