Question about Craftsman Garden

My wife was mowing the lawn and she hit a rock. Since than the lawn mower does not start and when it tries to start a little smoke will come out of the carburator area. The mower is a Sears eager 1 tucumsagh engine and is ten years old. I wonder if hitting the rock will it cause internal damage. Thank you

Unless the blade is belt-driven, like on riding mowers, then the blade is attached directly to the engine crankshaft. Hitting a rock with a mower like this is a very common problem. You probably have a bent crankshaft. In most cases this can be repaired, but may not be worth it, considering the age of the mower. But you should call a local small engine/mower repair shop to ask for an estimate. The repair is not something you would be able to do yourself.

Why when I couldn't start my toro 6.5 gts lawn mower with tecumsuh engine,I sprayed carb cleaner into carb and it started but smoked and knocked. what caused this problem?

bob if you spray carb cleaner in and it started that is a sign of not getting fuel. but if it is smoking and knocking you have a bad outlook for that engine. did you hit anything with the blades while mowing that caused it to stop suddenly? did you tip it on its side as the oil may have run in the carburetor. that can cause the smoking. does it have to much oil in it?

Mower hit rock won t start

I have the same issue, my wife hit a rock and now the mower will start for a second then quits. sucks because its brand new. I checked the oil, the gas, the spark plug, the shaft is o.k., even took it apart to check the flywheel shear pin and that's o.k. called the local mower shop and was told to go get another one! basically, the damage is internal and would cost more to fix than replace. this is done purposely by the manufactures. they don't make any money if you buy a $1.00 shear pin, new engine is much more profitable. this is coming form the repair shop.

I ran over a rock mowing the yard. the lawn mower sounds weird

when hitting things the blades get bent as well as the key on the flywheel meets the crankshaft throwing the timing off

I have a 6.5 self propelled Lawnman by MTD . It will start but will not stay running.

is the handle hard to pull?or pull back at times?any way pull the flywheel off and check the key that aligns the crank and flywheel in time they shear when you hit rocks

The engine is not started

Check the blade... it is bent and causes a vibration. if it is not the blade then the motor shaft is bent and that is terminal...if that happened then the mower is junk...

Start cord snaps back without mower starting

1.Check the plug for spark
2.Try a quick quirk of starting fluid to see if it runs. If it starts and dies then it is likely a fuel delivery problem.
3.   Check the shear key under the flywheel . Usually when it snaps back like. that the key is starting to shear which in turn would throw the timing off slightly.

Oil causing a problem?

Sound as if you have too much oil in the machine. Anytime you see white or lite gray smoke it is a sign of too much oil. Before you go through the routine of cleaning the oil out of every nook and cranny, try unscrewing the spark plug and clean it with a soft rag. It would have oil on it preventing the machine from starting. If this does work and there isn't a lot of oil in the gas tank now, just continue running the engine until the smoke clears. It won't hurt anything. But if cleaning the plug doesn't help you will have to empty all gas and oil from the gas tank, refill with new gas, squirt a little gum out carb cleaner in your carb to remove any oil there (this can be done when you try to restart the engine). Remember, when you are mowing grass if you are mowing on a hill) of any knd, make sure to turn the mower so the gas tank is on a higher level than the oil.
