If you try to pry it up with a screwdriver you will and probably crack the flywheel. There is a special puller that most part stores or small engine repair and sales that can be purchased for about $5.00. Hope this will help you out. Take it from experence, I broke one one time. That was enough because they are not cheep.

Hello mrcoffee4!

The armature is held on with 2 screws. Once they are removed, the armature just lifts off. The flywheel must be removed with a puller, as mentioned in the previous post. A bad armature or flywheel are not likely, and don't normally cause this kind of problem.

However, there is a key that holds the flywheel in place on the crankshaft that can shear off. If this happens, the engine's timing will be thrown out of adjustment. This usually only happens when the engine comes to a sudden halt....like when the blade hits a solid object.

Another possible reason for sputtering is carburetor problems. Give us a little more detail about the operation of the engine, like does it do it all the time, only when hot, intermittently, etc...
Have you changed the spark plug?

ty for your response chevy and cheese.
yes it doesit after i make 2 passes around my yard all the time.ihave switched spark plugs. it seems to do it only after it has been running a little while and is getting worse now. the armature wire was chewed up by mice so i thought maybe it was going bad or shorting out.

Ahh...ok. Now that we know the wire was chewed, it sounds like that is probably your problem. I would change it. Let us know how it goes.

i will let you know maybe tomorrow ty hopefully thats it.

i put the armature assembly on but i am not gettin any spark to the spark plug. it only had 2 wires and the condensor if im not mistaking they all hooked up to the same place. and the ground wire is hooked up to a screw on top of the assemlly where it was.coould this be an electrical problem in the ignition.and is there anywhere i cac get a digram to see that i have it hooked up right ty vm Larry.

Remove the ground wire and try to start it. If it runs you will have to touch that wire to bare matal on the engine or frame to kill the engine. If that does it, you have a safety switch problem, ignition switch problem, or the kill wire is shorted somewhere.

You may have bad points, misadjusted points, bad condenser, bad point cam follower. What I would suggest is connecting an aftermarket electronic ignition module. They are cheap, reliable, and easy to install. You don't even have to mess with the points to install one, just clip the wires and install the module. This way, you don't have to worry about points, adjustments, etc...

Sounds like your carb is flooding. It shouldn't be too hard to fix if you want to. Since you're this far into it, I would reccomend replacing the float, needle, and seat, and clean out the carb. That should get it running if the ignition is in time.
