let me get this straight... you WELDED the head on and a spark plug in? you probably just ruined that vintage kohler... GURRR  

Nope wrong The head is bad and 2 head bolts snapped And it was losing compression through the holes so i put weld in them and the spark plug holes were stripped so i welded a spark plug into the hole. Because i didn't want to put out money if it didn't run so its for testing purposes. And i didnt weld the head on and i didnt ruin the engine Just the head but it needs a new one anyway.

welded the plug to the hole? wtf? you ruined the block right there.

No i didn't. i pulled the head off and plugged the holes.

OK guys, lets try for helpful.

Craftsman, the head needs to be removable.... welding the hole shut probably permanently attached the head. best hope now is to grind the welded spot down till it comes off... The head is ruined in any case... the plug issue alone cinched that. If you can get it loose, toss the head, it's gone. if some of the shank is visible above the block surface, weld a nut to it and back it out. If it's broken off flush, take it to a machine shop.

We all do dumb things out of desperation, but the welder should stay away from the motor little brother.

I didnt weld the head on to the block i pulled the head off and i welded the hole there the head bolts go through. It was just something i did to see if it will run and if it fires ill buy a head but im not going to waste my money for something that isnt worth fixing.

You should of took the head off, extracted the bolt, installed a new bolt. Welding in the spark plug is stupidity, what if its your plug is bad? 2, you definitely torqued the plug too much. You could of killed the plug just by welding next to it.

and i bought this tractor for 100 dollars and the head was shot it was stripped when i got it i didn't tighten the spark plug to much someone else did and the tractors 45 years old. And its not like i'm going to run the motor with a messed up spark plug. I know the dangers the spark plug could fly out but What else am i going to do waste money on a engine that has play in the crankshaft has broken head bolts has a ceased carb broken coil bad condenser. More than likely i'm just going to get a different engine because this one needs a lot of work. I've already torn it down cleaned the insides out and threw it back together. And its not stupidity when i know the dangers and know what can happen. And its not ruining something thats already ruined.

you do know you could have extracted the bolts, right? at this point, extract the bolts, have the threads re-tapped, get a head, and rebuild it. it really IS a good vintage engine. as long as its not blown up, there really is no such thing as a BAD engine

I have tried to extract them but they are rust welded. And i dont have the money for a machine shop so i will probably Sell it and buy a better engine.

i presume that RedneckComputerGeek's candle wax trick would work. if not, is there any way to weld a nut to the broken stud? the heat of the weld should be enough to break it free, then back it out

I tried it multiple times and the nut just twists off so just ground them off and just put a ton of gasket sealer on it so there isnt any head gasket leaks.

welding on a spark plug wouldn't have told you if it would fire.... it absolutely wont after welding. The current induced in the coil from welding could have killed the coil (like lightening bolt inducing current in your phone line and burning your house phone up) The heat from welding the plug on likely melted the conductor inside of the plug as well.

It's good that you knew enough not to weld the head to the block, but this "Test" was never gonna tell ya anything.
keep in mind that some of these older engines are worth money... working or not. 805Roadking makes a good bit of money restoring these types of old engines. Broken studs are aggravating, but not the end for an engine.

Keep in mind, I'm not bustin yer chops.... I've been a mechanic for over 30 years.... you are relatively new to it... nuthin wrong with that. I'm trying to give you the reasons why this wouldn't work not just for YOUR benefit, but for others that wish to do this.

The coil wasnt connected when i was welding. i took it off

THE PLUG IS TOASTED NOW.... There is your point you needed to learn. 9 times outta ten, you melted the insides of the plug. if you didnt, im impressed.
Welding anything to a motor is usually a nono..

That's not redneck computer geeks idea, that method has been around longer than he has..

Um... the spark plug could be bad. but i put the coil back on when i was done welding. I tried to get it to fire up it didn't so i pulled the cord off the spark plug put a electric meter on it and it read nothing. so i cleaned the connections on the coil Still nothing. I changed the spark plug wire with a spare one i had. still nothing so then i put the one from me 10 hp kohler that runs still nothing I checked the points they were fine but cleaned them anyway still nothing so its obvious the coil or the condenser is bad. And if i get a new coil and condenser and it has spark but the plug has none then ill get a new head but untill then im not putting money out. Im still in the middle of a project when thats done ill think about putting money into the motor to restore it. And repair it.

well thats where i heard it from...

as Solomon said, "there's nuthin new under the sun"

a lot of folks refer to redneckcomputergeak's vid, it is a good demo of an old technique. Giving him credit is no slam on whoever first came up with the idea

When i bought my 72 cub the wiring was chewed threw so yesterday i pulled all the wiring out. Cut 2 of my knuckles while doing it. And started scraping of dirt. So i can start measuring the frame to see what engines will fit in it.

unless i missed it, what are your plans for this cub?

My plan is to get a running motor put it in the tractor and make it a plowing/work tractor. And maybe restore it if i decide to keep it.

Got the throttle and wiring disconnected. Cut 2 knuckles in the process.

Went to clean the gas tank and the bowl and it wa cracked and it split and the gas tank has a ton of rust don't know if its worth fixing.

Got the carb soaking in kerosene

Got the holes cleaned up now i'm going to try and fill them in with weld.

ok so tonight i tore apart the cub i worked on it for 3 hour until it got too dark to see had a lot of rusted bolts so it was a pain. got it down to the frame trannys still in it because i'm going to tear it open tomorrow to look inside. tractor needs A LOT of work. and i was debating just using it for parts but what do you guys think should i restore it or part it out. i would like to start working on a racing mower and a mudding mower. let me know what you guys think i should do. Ill post pictures tomorrow.

Id hate seeing this going to pieces, but this doesnt HAVE to be done now. what id do, is take it apart, label everything you're gunna keep, and bag it up and store it, push it to the side if you're thinking about a racing or mudding tractor.
