I guess I could have explained more thoroughly I have changed the air filter and fuel filter and changed spark plugs and also disconnected the kill swithes on mower to make sure that was not it either plus I changed the oil too
It could be that the mixture is a little on the rich side. Close (rotate clockwise) the needle valve on the carburetor about 1/8 of a turn.
fuel filter
your neon sputters from old spark plugs and plug wires. i changed both and problem went away.
there is actually no problem. it sputters because the engine has to start up and it may be the way you place the key inside the ignition. so don't worry because it isn't a big problem
Had the same problem, try changing the plug wires, it worked for mine
If this occurs, then it means that there is a problem with you engine. A mechanic can figure out how your engine should be fixed.

souds like a fuel problem not getting enough fuel.
can you tell me if this problem is with a idle air valves control on this Cadillac Seville sls 1996
If your Ford Aerostar sputters at high speeds, you might have a problem with the fuel injection system or with the fuel filter. You could also have water in the fuel lines, bad gas, or even a spark plug fouling issue.
I had the same problem with a jeep wrangler and I replaced the throttle position sensor and that solved my problem.
I am assuming this is a problem on a high mileage car? It most likely is a problem with the carburetor. The carborator is likely dirty, so take it out and give it a good cleaning with a toothbrush. But due to the lack of details i have no idea what the problem really is
