Hello and thank you for choosing Just Answer. My name is XXXXX XXXXX I will do my very best to assist you with your question. How are you today?
Thanks ... Do you have the model number for your mower available? With this information, I can look up your mower.
I believe your brake lever is not releasing and this is causing your rear wheels to lock. After I look up your mower, you and I can do some troubleshooting.
It appears that you are experiencing difficulties staying connected to our chat.
can you read this chat?
Yes, thanks, XXXXX XXXXX it now. I will attach a picture for you. This picture will assist us with troubleshooting your problem.
Did this problem happen all at once or was it gradual?
It wasn't gradual, just all of a sudden stopped working. And because it's stuck in gear i can't get any spark
Thanks for your response. Let look at the picture I attached. Number 26 is a 7/16" bolt. There are two of these bolts. In the middle of these two bolt is a 1/2" lock nut.
That 1/2" lock nut is used to adjust your brakes.
I would like for you to use a 1/2" wrench and turn this lock nut counter clockwise in half turn increments.
ok, give me a minute to do that
This test will indicate to us if your brakes are locked and causing your wheel not to turn.
i did it about a half a turn and something broke loose and the wheels aren't locked now.
Since your transaxle will shift from forward, neutral, and reverse, your transaxle should be in good condition.
Bingo ... we did it!
just tried to turn it over and still no spark.
Your engine will turn over and spin, but will not start up and continue running?
there's no spark to the spark plug. i thought the reason was because it was still in gear. The plug is brand new.
What type engine do you have? Briggs & Stratton, Tecumseh? Kohler?
briggs & stratton 5 hp
How did you test your spark?
took the plug, attached it to the plug wire grounded it to the manifold and anohter person turned the key
Thanks for information ... you will either have a faulty safety switch or a faulty ignition coil. i can tell you how to test to be sure.
If you remove your engine shroud, you will see your ignition coil. There will be one wire that plugs to the terminal on your coil. Unplug this wire and retest for spark.
If you get spark with this wire unplugged, then your coil is good. If you doesn't get spark, then your coil is at fault.
did not get any spark with wire unplugged
I afraid that you may have to replace your ignition coil. With that wire unplugged, you eliminated all of your safety switches relating to your coil. I have something else for you to try first.
There is a magnet on your flywheel. Take a screwdriver and hold it near this magnet. Check to see if the magnet will draw the screwdriver strongly to it. Also check to see if this magnet has a lot of rust on it
The whole flywheel and coil have a lot of rust
Ok, if you clean the rust from your magnet and your coil, this may solve your problem. I can tell you how to do it.
Okay I can take care of it from here. Thank you for your help.
You are welcomed ... Remember to set the gap between your coil and flywheel at .010
hi, i installed a new ignition coil and still no spark. Any ideas?
gap is set to .010 and unplugged the wire and still no spark. Which wire might be going to ground?
Yes i tried the flywheel magnet and it's strong. Sorry, this was a reconditioned engine when i bought it, so there's no model number that i can fi nd.
Briggs and Stratton, hp 17.5, i cleaned the poles that the coil mounts to and the flywheel magnets. the coil is brand new.
i'll give it a try. thanks
Hi, i put it all back together and fired it up--works now! I'm not sure exactly what it was. Maybe there was a spark and i couldn't see it? Anyway, thanks for your help!!
