I have an old roto tiller I bought for $20 form the interwebs... has an old Techcumish engine with no spark. Looks like this may just be my dinner.. Thanks Taryl and Slip dog!
So the original tractor had a solid state ignition? That surprised me. Interesting seeing a coil used to save a vintage tractor because solid state is NLA.
I'd be tempted to either paint the coil red or white, or cover it with a chrome cover. That blue coil is like a stain on an otherwise beautiful tractor!
It's been many years since school, but if I remember, solid state systems produce around 20,000 volts while standard coils produce around 30.000. Hence the hotter spark. There are advantages and disadvantages to both systems.
@@jimbrewer2893 Farrraday documented and then wrote the formulas for the "flyback effect" of a magnetic field when the circuit that was creating that field is instantly halted. If you get creative to maximize the effect with two separate coils of wire that's the classical magneto or battery coil system with mechanical contact points. The voltage available is theoretically INFINITE in any such system. Skip now to what you are trying to accomplish with such a system- jump a spark gap. Doing it while the gap is inside a pretty fair vacuum and also while same gap is inside couple-three hundred PSI is not too demanding nowadays we got good insulation to keep that voltage from going anywhere except the gap. There's always gasoline or propane or something mixed in with the air. If it's mixed real thinly (lean) then a big gap and a long spark duration are very helpful. If the plug is sooty or wet then making the voltage at the gap jump up so fast it goes across the sooty wet surface and across the gap and still starts the engine. Battery-and-coil builds up slowest - a good magneto is pretty good at it - and best of all is CD capacitive-discharge ignition which is why it gets used in two-cycles, outboards and the like - most beneficial when starting. There - now you know just as much as i do on the subject.
@@patrickshaw8595 It's fun to see guys change out ignition parts from a "yellow" spark. Using a real spark tester, don't worry about color. That's from some crazy 💩 burning ions out of the air or something 🤣 Can it jump the spark testers gap is the main question. These ol dogs don't need much spark to run,and the timings fixed. After all these years now Briggs has an electronically advancing ignition on the newer bigger engines ,and it's given them a bunch of power.
I did something similar with a 1969 Bolens 1455. I made what is usually referred to as a "dirty" power supply. I hooked that up to pickup coil under flywheel, and hooked that up to an early 70's GM ignition module to fire ignition coil. Ignition module had to be mounted to an aluminum plate for cooling itself. Just cut a 3x3 square and attached it to blower shroud. I also added a wire with a diode to the "start" on the original key switch so engine would have spark during cranking. Years ago I drew a diagram for Bolens, it should be floating around the internet somewhere. Best tip I can add to this is, pay attention to where 12v is going cause you can, and will burn shit up IF not done right, and think things through.
Excellent. HEI came out on GM cars in '75 and I think I did my first HEI conversion on one of these about '77 or '78. You might have beat me to it. However I figured out by about '93 that "everything except the distributor" from an '88 5.0 Mustang worked really really nice and trouble free.
@@patrickshaw8595 Yes, they work fabulous! Keep in mind, the reason for using the early module was the early GM ignition did not use any computer control. God bless
Thanks for showing the crimp tool, Im going to buy myself one of those for Christmas. I have one of those tractors, so Im going to look up your buddy Dale. Nice piece Slippers. Good job on the wiring Taryl.
I was probably the first one to make a substitute for the original system while still a teenager. Used the battery charging coil from an electric start Lawnboy handmower next to the flywheel as an inductive trigger for a standalone GM HEI module with the 6-cylinder HEI coil. I had to tune the offset input voltage to the module with 4 tiny diodes and a resistor to come up with 2.1v. It worked well but because the ignition coil was energized for a fixed crank angle (there was no way to use the module's adjustable dwell capability) if you left it idling too long the coil was subjected to "on" times longer than 3 milliseconds and it would eventually overheat and short out. If you had it running at least 2800-3000 rpm or up then it was fine. Other than this kit Taryl shows the easiest way to scratch build an ignition for on of these now would be to epoxy tiny super magnets to the flywheel's periphery, use any automobile Hall Effect sensor (that you can find the wiring diagram for) hooked to one of the remote mounted Ford Thick Film Ignition modules. 1) It would work at Zero Rpm. 2) It would adjust to the correct dwell if paired with the correct coil. 3) Get the parts from 1988 Ford Mustang 5.0 called "the push-start module" ($90 for everything from NAPA)
I have a couple of old antique pieces of equipment. A DR wood chipper with a 12 horse single cylinder Tecumish on it and a 2004 Scrub Cadet LT 2042 with a Kohler engine and shaft drive. They aren't really antiques, they're what I use to maintain my place. The deck on the scrub cadet needs welding, Tecumish stopped making spark while I was running it last time, so thanks for this video. It's probably going to come in handy.
Good info Gentleman. Thank You ! -Now about that *TECUMSEH ENGINE* decal on the engine, I don't recall any of my History books in school showing *TECUMSEH* LOOKING LIKE THAT ! 🤣
No need to hide that coil it looks good That Ignition upgrade is better than the original I think anyone with the same setup would be wise to change to that system
Happy Father’s Day Taryl and Happy Father’s Day to everyone you are the man Taryl thanks for all your videos and the time you and your family take to make them,you are loved here in Van Buren Twp Michigan Taryl.
Tarly your awesome.....when I retire I’m gonna open up a small engine repair shop.....it has always been my favorite work since I’m nine years old...had guys tell me that’s will never run and I always getter running
Happy Father’s Day Taryl. Slipper is lucky to have you there to fix up his and juniors mistakes. Onward and upward, get ‘er done, there’s your breakfast!!!
I did the same ignition set up on my 1967 Sears super 12 it originally had the Tecumseh with points, but that motor is long gone, someone put a tecumseh solid state motor on it and the solid state died on it, so I put this overnight solution kit on it and it runs the best out of all the sears mowers with the Tecumseh solid states that I own
I’ve got one of these tractors, & got rid of the stock engine initially cuz I didn’t want to deal with it. Edit: I still have it & yes the old coil does work & the engine does run. The wiring harness on the tractor itself is all junked up from sitting outside.
All I could picture is the scene from Back To The Future III when Doc wires up a new time circuit using 1955 parts and the thing is just strapped to the hood of the car :D
Man I had sold state ignition on my HH100 on a wheel horse. What an expensive problem child! Went through 3 of them the stater kept burning out at 200 bucks each time for a Kohler. End of problem.
Great professional repair that really befits that nicely restored Sears tractor. Good demonstration of knowledge and skill. Always look forward to your videos. I guess Junior should stick to sweeping the floor.
I have that setup on an OH160 Tecumseh that powers a Miller welder/generator and you honestly could not ask for a better product, now if it were not so difficult to find carburetor parts for those old HH and OH series cast iron Tecumseh engines.
The instructions say to mount the coil away from heat and vibration. Seems mounting to the head bolts would cause a premature failure in a day to day use situation. (From instructions: 6) Mount the ignition coil and Transdenser II away from heat & vibration ---
You boys are lucky to have a Dad like that.
Happy Father’s Day Taryl.
Been watching you for years and you are the mistro of upgrades on vintage machines. Great vid!
I have an old roto tiller I bought for $20 form the interwebs... has an old Techcumish engine with no spark. Looks like this may just be my dinner.. Thanks Taryl and Slip dog!
I love watching the talented Dactyl family on Sunday !!!! Another great production fellas!!!!
It's like watching the Sinclair's.
"Not the Mama!"
Just bought a 10XL from the scrap yard! Appreciate you showing me how it keep it operational!! 🇺🇸🇺🇸🇺🇸
This YT channel is the best on DIY - How To - small engine repair. ✔
Happy fathers day taryl
Beautiful restore job on that 10XL.
Great that you are helping keep old Tecumseh's rolling. Good on you.
Happy Father's Day guys. Taryl Sundays are the best. Wish I new about that company last year.
I have 3 Tecumseh HH-120 12 hp blocks and this solves one of my problems .
That's a great looking tractor.
So the original tractor had a solid state ignition? That surprised me. Interesting seeing a coil used to save a vintage tractor because solid state is NLA.
Slipper clutch did a fine job of renewal on that Sears, beautiful restoration. I'd give him a There's your dinner on that one.
I'd be tempted to either paint the coil red or white, or cover it with a chrome cover. That blue coil is like a stain on an otherwise beautiful tractor!
Well done nice job what a good little Tractor cheers Mick Australia great site.
Enjoy watching you repair the equipment hope you had a great Father's Day thanks for the video
It's seems like it has hotter spark and gives the tractor more torque and speed. Great job guys.

That 10XL is mint. You guys not only did a great job restoring it but all the colors chosen are perfect.
HAPPY FATHERS DAY Taryl..... and all the other "Grass Rats" Fathers
To you too 👍✊
Glad you got the 10XL back to life, one of my favourite projects you did! It is just an amazing tractor 👍🏻
Thank You Taryl another great lesson , I restore old garden tractors and Electrical issues drive me to drink a lot of beer , Helps me to calm down
Man look at that gorgeous little tractor!
That’s actually an awesome upgrade I love that 10XL and how it turned out…
That's one nice looking tractor Slipper's! Good job guys!
Happy Father’s Day!!!! That’s an awsome classic tractor slippers!!!!
Thank you tayral for being a great teacher
Thanks for part numbers Taryl. always got to have part numbers. the more part numbers the better. Thanks Taryl!
Wow. That is one fine looking tractor. Such a cool upgrade.
That is just like the 1970 thru mid 80s boat ignition system happy Father’s Day I got 4 boy boy girl boy 👍🏻
That's the exact coil that came off my 74 VW bug 🙂
13:12 “and then you’re going to get mad and start throwing stuff”. Typical Saturday in my garage fixing something. 😅
Why would the day of the week matter? I get mad every day of the week and through stuff, keeps me in shape!🕶
That tractor is clean! That new spark is red hot!

I have the exact same mower with no spark. Gonna get ahold of Dale at overnight. Thanks a bunch for the video.
Hit up Dale over at www.overnight-solutions.com
What a beautiful machine, definitely worth saving!
Love the paint job on it
Very sharp tractor
You guys are the best! I hope you guys had a great Father’s Day and take care! Keep up the great work.
That is a nice old tractor, and you did a nice job on the wiring, great job .
I am gonna have to check them out. I've got an 8hp vertical shaft that dies after it gets hot. It starts OK when cold. Thanks Taryl!
Thanks for showing the crimp tool, Im going to buy myself one of those for Christmas. I have one of those tractors, so Im going to look up your buddy Dale. Nice piece Slippers. Good job on the wiring Taryl.
Lol 1931 was a good year...nope is was not..Another Great video guys.
This guy like a vo=tech teacher man!!!
That is a slick updated kit for those old Tecumseh engines
I'm definitely looking into this. I've got seven of these old Sears tractors, and it would be nice to get them running again.

Please do! Those old girls are great tractors that far exceed the quality of what they are producing today.
Good video!! I once put Chevy coil on a tecumseh, it worked well!!!!😎👍
Get down Daryl! That bolt with a stud was a great idea. AND Overnight Solutions👌
Fantastic looking restoration!!!
That is actually a really cool looking tractor
Same Bosch blue coil that's on my VW bug.
I have a couple of old antique pieces of equipment. A DR wood chipper with a 12 horse single cylinder Tecumish on it and a 2004 Scrub Cadet LT 2042 with a Kohler engine and shaft drive.

Good info Gentleman. Thank You ! -Now about that *TECUMSEH ENGINE* decal on the engine, I don't recall any of my History books in school showing
*TECUMSEH* LOOKING LIKE THAT ! 🤣
Looks like that thing would run HOT!
Where do we get that decal? I have been missing the Indian maiden on the butter packages as well.
No need to hide that coil it looks good That Ignition upgrade is better than the original I think anyone with the same setup would be wise to change to that system
Good goin' guys, Taryl to the Rescue.
That tractor is awesome great work boss!
Great video guys GOD BLESS YOU ALL Andy there's your Dinner
Happy Father’s Day Taryl and Happy Father’s Day to everyone you are the man Taryl thanks for all your videos and the time you and your family take to make them,you are loved here in Van Buren Twp Michigan Taryl.
Tarly your awesome.....when I retire I’m gonna open up a small engine repair shop.....it has always been my favorite work since I’m nine years old...had guys tell me that’s will never run and I always getter running
I love you ALL! Great fun and videos! Thank you!
That's awesome. Thanks for that information. Happy father's day
Great job Taryl happy Father’s Day i’ve done that once or twice in my life 👍
Love watching the videos really gives me the giggles
i love you man . i learn so much . i work for a pawn shop in Brooksville fl Steve
Thats a beautiful tractor. I wish my Bolens H14 looked that good.
Happy Father’s Day Taryl. Slipper is lucky to have you there to fix up his and juniors mistakes. Onward and upward, get ‘er done, there’s your breakfast!!!
Thats a great kit, i have an old john deerethat has been converted to coil ignition,works great
That was supposed to be the great taryle himself
Oh man it's 130 am...
Working all day... Still got no sparks. Overnight solutions you say...
Threaten me with a good time... Your on. 3 2 1 go
Slip-dogs garden tractor does look great. Aaakktchooolie, it's badass.
That’s pretty cool I wonder if you could use something like that on a break
i can see Slippers re-painting that coil and tucking some of the wires out of sight.....looking good
I did the same ignition set up on my 1967 Sears super 12 it originally had the Tecumseh with points, but that motor is long gone, someone put a tecumseh solid state motor on it and the solid state died on it, so I put this overnight solution kit on it and it runs the best out of all the sears mowers with the Tecumseh solid states that I own
I can see how Slippers would want to be careful because of the nice paint job.
That's why I like the old Sears custom 6-7-8s. Same tractor with points.
This is a good upgrade, I love that 10xl tractor if looks great. Happy Father’s Day
Happy Father's day my friend
You brought joy. Thanks!
Those overnight solution kits work well. I've had sears with the Tecumseh engines for a long time. Fortunately only one ignition ever failed.
Taryl is doing all the work!!

Happy Father's Day Taryl
Now its red white and blue, cool.
Great video. Happy Father’s Day!
Nice job! I love how the external coil looks. Taryl indeed does fix it all...!😎
Dang what a sweet rig!
Looks like a 1st gen tecumseh solid state.i was told if u can get to the boards its a 1.50 fix
Love it when it all comes together
Sounds like you got a hotter spark with that coil
Seems like the heat is gonna be a problem for the coil location.

hang on to that old stuff!
never never let the smoke out !
Hey! That Bosch coil looks just like the ones I used on my Air cooled VW's!! : )
I like the crimping tool gotta get one of those !
