These Tecumseh vertical shaft L heads are some of the best mower engines I’ve ever owned.

[@TheLawnmowerLady]

When taken care of, they do last. Thanks for watching!

[@garygary8645]

I'm also a Tecumseh fan. When you give them a bit of maintenance, they run great. Thanks for the video, Stella

[@TheLawnmowerLady]

Yes they are! I appreciate you watching.Cheers!

[@BrucesShop]

All the tecumseh motors I have worked on and did not know about the F on the bowl. Thanks

[@TheLawnmowerLady]

Hola Mr Bruce! I kind of figured that out on my own. I've scoured many a service manual, and never saw mention of that. I can't figure what else it would mean? On the older brass floats, you could see a witness mark from that divot to determine the orientation, not on the plastic floats. Cheers.

[@billdeblaey6078]

Just today I pulled out my old Tecumseh powered Toro. Probably 20 years old. Havent used it in months, but wanted to use it to chop up leaves. Put fresh gas in it, primed 5X, and it literally started on the first pull. Slight oil leak on left side near the base of the engine, leaked about a teaspoon after about an hour of hard use. Don't care, runs strong and is my ditch/leaf mower.

I love those old Tecumseh engines, I love the carbs because I can usually just drop in a 631021B kit in them and maybe a new primer and they are good to go. I absolutely love your laser rig and your large tray for under the mower while you change the oil. Two great ideas!!!

GREAT JOB STELLA.. I myself like these old craftsman.. with regular maintenance they run forever and forever. They are beast. CB

[@TheLawnmowerLady]

Thanks!!! I agree 100%

[@TheNovaJohn]

Nizeee Just got another nice one in yesterday on trade,,Needs a bunch, crank seal it bulging,, wheels shot,,adjuster very loose BUT its super clean,,,paint has like no scratches or ROT on the deck! Nice job,,,, I clean all my machines, the pull starters do get jammed up, these get cleaned as well when pressure washing, Oil or chain lube on most, also up into the spring area as well. NO oil on briggs, the plastic palls wont grab,, chain lube or chain wax combo. and these get wiped well after.. I do charge more for this but the machines that I do look like new.

[@TheLawnmowerLady]

I usually clean in a desperate attempt to keep the shop and my hands a tiny bit cleaner, 😂 I do squirt some WD-40 on those plastic Briggs pawls. Never seen a problem, I see so e of the same mowers year after year. Thanks for watching. Cheers!

[@dirtyberniesgarage1194]

Great job on the fix! It’s to bad that Tecumseh gets such a bad rap, I think they are great engines

[@TheLawnmowerLady]

I think most of the Tecumseh hate is from Europe, those were made in Italy, and unlike the pinnacle of scooter manufacturers in the 60s (think Vespa and Lambretta), everyday was Monday at the Italian Tecumseh factory. Heh!

[@ClassicTVMan1981X]

My 1984 Toro with its TNT100 is still going strong!

What a difference. Great find lady.

[@michaelreynolds1892]

Had one do the same blade a little loose, sounded real bad, tightened and ok.

[@TheLawnmowerLady]

I'd suspect many a lawnmower went to the dump for nothing more than a loose blade!

[@mikehrdlicka8635]

I got that same mower along curb last fall. Someone replaced carb with a foreign one. Cleaned it ran lean. A original bottom jet fit it. Lots better drilled upper one runs great

[@TheLawnmowerLady]

These older mowers are better machines than almost anything you can purchase new today. Thanks for watching.

I’ve heard that noise before. I was thinking, take the blade off, reseat and tighten. Glad it worked out.

I probably should have, but it seemed awfully secure on first impression. Besides, it would have been a far less interesting video... Cheers!

[@TheLawnmowerLady]

Thanks, you too!

[@andysaunders3708]

Nice. Have always loved the Tecumseh engine, as it had an actual oil-pump, as opposed to the BS splash rotor, so you could use them on quite extreme slopes. They made them under license in Australia years ago as the "Kirby-Lauson, and also, the Spanish government "nationalised" the 2 stroke version, moved a few bolt-holes around so genuine parts wouldn't fit anymore, and renamed them "Aspera". They were still good.

[@TheLawnmowerLady]

I appreciate the history insights. I have some old parts and literature that mentions Lauson. The Kirby connection was news to me. I guess they were trying to compete with Electrolux. Thanks for watching. Cheers!

[@chrisssmallengines7163]

Nice mowers , I like them good mowers they love to have clean oil in the crank case . You have to make sure you dump junk into the gas tank , because the main jet pick up is so low in the float bowl . I use one for my personal mower .

The more I learn about lawnmowers the more I realize the products of the past were just more durable and simple to work on. In terms of durability what is your opinion on the Tecumseh vs Briggs and Stratton motor?

[@Rein_Ciarfella]

Not just lawnmowers! Just about anything you care to mention with few exceptions.

[@TheLawnmowerLady]

I think this later model Tecumseh is right up there with the flathead Briggs, often referred to as the Quantum engine. Even the older 3.5 Tecumseh engines, I think is just a bullet-proof as the older 3.5 Briggs pulsa prime engines. I think the Tecumseh engines get such a bad rap across the pond is they were made in Italy. Not unlike licensed manufacturers of antique Vespa and Lambretta scooters in the 60's, made in Asia, South America, and other parts of Europe. Just enough difference to make them not as desirable as the originals. I really appreciate you watching. Cheers!

Good video Stella the Techumseh engines are pretty tough the only think i do not like is how the primer bulb stiffens up but it still works.

[@TheLawnmowerLady]

Surprisingly, this one even with its advanced age, still worked. Some versions were black rubber, shaped more like the Briggs 9nes. Never figured if they were interchangeable. Cheers!

[@waynestefinashen239]

@@TheLawnmowerLady Interesting thought never tried to swap one out ie: black for red may look through my spare scrap parts carbs and take a look at that.

[@haneyoakie14]

I love the Tecumseh TVS engines. As you mentioned, they were better made than the 2023 engines are. Obviously, that one is at least 15 years old, Tecumseh went belly up in 2008, and that one actually looks like a late 1990’s model to me, maybe 1998, so 25 years old. If cared for, that has 25 more years in it.

Briggs engines can run ok with a partly sheared keyway but even a hair off on the Tecumseh you'll get a kickback. That one may be very slightly off.

Stella, I’m looking for a specialized source for seals. I came across a reference to one a while back but can’t find it now. This source would have low minimum orders, good pricing and normally sell to small engine shops. I want to order by seal dimensions rather than OEM part numbers. This would be for things like small 2T (string trimmers) up to 4T (lawn tractors). Any help?

[@TheLawnmowerLady]

I used to google the dimensional numbers, and got good hits for suppliers. That said, I never felt the need to stock much more than common spark plugs and air cleaners. I usually just ordered them one at at time. Yes, I paid more, but I pass that cost onto the client. I appreciate you watching. Cheers!

What did you tork it to?

[@dougsorensen7594]

I've learned so much from you. Question - I have a silver and black craftsman 20in with the 3.5 Tucumseh engine. I maintain it well. Use only ethanol free gas and stay-lube. The engine runs fine up steep hills and down steep hills, but on steep sidehills it dies and then is hard to restart. I checked the carb, cleaned it etc. But it still stalls on steep sidehills. Do you have a suggestion that I don't know of? Thanks for considering my question.

[@TheLawnmowerLady]

On those side hills, you are fighting gravity. The float in the carb bowl can't regulate the fuel flow on those side slopes. Depending on which side, once you get back to level ground, you are either drowning in fuel, or starving. I suggest mowing those slopes on a diagonal. Thanks for watching.

[@dougsorensen7594]

@@TheLawnmowerLady Thank you for your thoughtful suggestion.

[@xuchao9098]

remove the carb float ,and install a Fuel Shutoff from outside. manually shutoff the fuel when you stopped the engine .

Mower starts and cuts out....when I hold primer button in, pressed in it runs good, I just replaced primer button...if its not seated and sealed, could this be my problem, it's the older Tecumseh

[@TheLawnmowerLady]

Could be. That would allow more air in, and you holding the bulb in seals it tight.

Hi Stella. Why don't you buy yourself a vacuum oil changer. It will save you a lot of mess.

[@RaysLaughsAndLyrics]

With a bit of help from Norm, The mower be now reborn. The Rays of Ruby Red light. Now proves shaft is alright. A keyway shift not the error, Not cause of vibrating terror. The pull start lubed and fine Starts on one pull each time? Air filter an' spark plug are due, Says the lady dressed in blue. Oil is drained from the crank. Some was spilled, let's be frank. Oil now added to proper depth; Starting Tecumseh is all that's left. Start Noise remains off camera. It's such a perplexing dilemma. Sometimes a simple screw loose Will surely, now, cook your goose. Tighten the bolt for mover blade, The vibration now did finally fade. Stella stayed the difficult course. And fixed the three an' half horse. Twenty-five years it did cut grass, Twenty-five years more it will last.
