Gary, I too have a YT Craftsman I bought new. It's been a great machine and I wouldn't take for it but it just went kaput. I think it may be the same thing wrong with it as yours. Turned the switch on and it acted like it was going to start as usual, then kaput. No matter how many revs it turned over, it wouldn't even fire. That said, I will follow your excellent video and see how it goes. Thanks very much. Great video!
I don’t think I showed it in the video, but first check that the valve lash is set properly and then spin the engine over slowly by hand. On the compression stroke you should see the intake valve bump open just after it closes. Also try taking the air filter off and hold your hand over the intake. With your hand over the intake, try start the engine. This will restrict the amount of air being compressed allowing the engine to turn over. Thank you for your comment.
Magneto/magnets will need attention. They are easy to replace. Great work and video getting that old gal going. Just worked on one to use as a softball field dragging tractor. Enjoyed it greatly.
If you look at the u.s. as the haves and the have nots and you cam tell the difference by the wasteful spending and lack of effort they put into fixing things or just buying new. Every spring the curbs are loaded with big flat screens that still work but one house got a new one so everyone got a new one. And people are getting lawn service so mowers aren't needed as much. It's funny they will give some things away but sometimes they'd rather push it off a cliff rather then let someone else have it.
adding 1 ounce of two stroke oil per 5 gallons of gasoline will keep these platinum engines running forever and they will not use any oil. I have a YT3000 that runs like its been charmed since 2018. I bought the machine used for 200.00
I have a very similar mower that just took a dump. It sounded like i hit something and sheared the flywheel key. The engine died right away, although i couldnt locate anything i might have run over, maybe a rock, but its seemed pretty low in the ground. Anyways, I replaced the sheared key and it still won't start. Could it be a crankshaft issue like yours if the engine is freely turning over with the spark plug in place? I have fire, and im pretty sure i have fuel. There is an air leak sound coming from the oil canister, and i have yet to check compression.
I suppose if the decompression mechanism fails and falls into the gears it could jams and cause the engine to stop. However, if your engine turns over freely, I doubt that's the problem. If the engine seems to spin over faster than it normally does, than you may have a broken camshaft gear. Unfortunately, you may have to pull the sump case off to find the problem.
Mine had the exhaust popping back up thru the intake plastic pipe. I adjusted valves and runs fine. Well its being dropped in a stiga park president. Motor up from 12.5 to this 21. By brain cant follow wire looms so i squealed like a lil girl when i saw the key switches are the same. I just swapped ignitions and hooked up the stiga loom. Then the party was over again because of the clips on the motor are different. So no i have to figure out where to plug the magneto wire, the fuel solenoid wire, the kill switch wire and i need to add a pto switch. Im at the head scratching stage now.

Thank you for the kind comment I appreciate it.
Nice job! Would love to see that old snapper in the background running!
Someday I would like to do a full restoration on the Snapper riding mower. I think they are pretty neat machines. Thanks for the kind words!
Nice work getting it back going
Thank you! I appreciate the kind words!
Thanks for this. I've got the yt4000 and I've learned a thing or 2 from your video.
Thank you for the kind words!
I luv Jersey ! Graduated college from there.
What part of Jersey ?
@@GaryAhl Drew University in Madison. You sound like a South Jersey guy.
@@PapaMav Yep, South Jersey surrounded by farmland.
People never give nothing for nothing in NZ you guys are so lucky in the states
It’s not that common here in the states anymore.

We used to add 2 stroke oil to the gas in our demolition derby cars back in the day. Certainly can’t hurt the mower when mixed properly .

I hope that aftermarket works they say it’s best to bite the bullet and buy the factory one
I was seriously considering sending it back after seeing the plastic keying the decompression mechanism together. Thank you for the comment.
@@GaryAhl yeah I could tell but hopefully the jbweld will hold it and your welcome
Spotted a Taryl mug !
I do enjoy watching Taryl. Thank you for the comment.
@@GaryAhl me too. Thank you.

It doesn’t always go as planned but there’s nothing more satisfying than working through it and getting it running.
Low voltage??? Check valve lash before replacing camshaft
I know what the problem is.. it's a GMC. ... I mean a MTD
Lol
I think I would superglue the cracks in the magnets and see if it helps
I’ll keep your suggestion in mind for the next time I come across broken magnets. Thanks
