SOURCE: lawn boy 2 cycle mower won't start

Replace the spark plug and retry.
If a new plug does not work push the spring button on the bottom of the carburetor to make sure fresh fuel is in the fuel bowl.
if this does not work remove the spark plug and squirt some light oil (like wd 40) right into the spark plug hole; roll the engine over slowly a couple times using the starter rope. put the plug back in and snap the plug wire in place. If the mower now starts after a couple pulls it means the rings are worn, replace the rings.

SOURCE: The rear wheels will not turn in reverse at all. I

Rear wheel drives like this have pinion gears with rachet pawls that allow them to go backwards freely while locking when the transmission drives them.

You need to take off your rear wheels and carefully remove the pawls. They look like little squareish metal shaft keys with springs under them. You should notice that the keys or pawls are covered in what looks like grease.....which is actually worm metal from the pinion gear and oil mixed together to form this pastey greasey substance. Clean all that stuff off and lightly oil *( light oil...3 in 1 kind of oil) and reassemble.

You should hear the nice clean clicking of the rachet pawls as you roll backwards again!

Good luck and be careful!

SOURCE: can you run your lawn boy mowers without the

Yes you can. The only reason small engines have the primer button/bulb is to get gas to the carburator to make it easier to start it. If your mower starts OK without using the primer bulb you will not harm the mower.

Tecumseh 13hp overhead valve snowblower engine starts fine than sputters and dies, replaced the carb with new and exact same symptoms, Lots of fuel at the carb.


Make sure the fuel is good. Ethanol laced fuel starts to varnish after 20 days and is no good by 30 days, it also attracts water. Be sure you have good fresh fuel, then try a new spark plug.

I have a Lawn Boy 10685. Changed the blade and went to start the mower and the pull cord will not pull. I tried spinning the blade by hand with no luck. I took the starter apart and it spins fine. I check...


Remove the spark plug and try pulling the starter again. You may have a fuel leakage into the cylinder and it has caused a hydraulic lock. Check/change the needle and seat in the carb as this leaking is the usual cause if this type of problem. Good luck and please rate this solution.

Lawn Mower will not stay running then will not restart


I think we all understand the frustation penaone.
I noticed u didn't clean the fuel tank, water, dirt, and rust in it can give u problems. But u need to clean the lines and carb. again also. One of the kids filled my mower gas tank with driveway gravel once, and after I cleaned things out, the mower never run so good. Also your spark may be grounding out somewhere before it gets to the spark plug. Check for a bad spot in the wires from the magneto. Some of that may be behind the flywheel though.

Engine will not start, no spark


Try taking of the engine shroud and cleaning the magnets on the fly wheel. Also clean the two little prongs that are really close to the fly wheel. Use fine sand paper or emery cloth. Then check the spark plug wire for rust (clean if any). Try replacing the spark plug if it is old.

Let me know if this helps.

Engine won't start . Pour gas in cylinder it starts then quits.


hi lou. your carbeurator is gummed up. It will need to be removed, soaked in carb cleaner for three hours and then rebuilt using the correct kit.

if you are not familiar with how to do this i recommend that u have it done by a lawn mower pro
