I was cutting grass when the mower acked like is was running out of gas, and I knew it was close to being empty. I filled the tank, started mower and it sputtered on any speed above idle. I thought it might have sucked trash into the filter, or fouled a plug. replaced plug and fuel filter. now the unit only runs with choke open. when i adjust the throttle to any other position it quits. Any suggestions?

Greets...
Nothing specific comes to mind..... However...
By using full choke you are cutting down air.... which could mean and air leak somewhere ( gasket, air hose ) It can also mean the carburetor is not delivering enough fuel.. oddly enough and by using full choke you are forcing it to draw more fuel from alternate carb. source. (let me muse a bit here)
If I remember correctly the Sears mowers use a settling bowl arrangement on the carburetor. And in it are at least 2 fuel jets or holes that lead to jets.... Make certain these are clean...(your idea on junk from tank may be right) Sometimes just taking off the settling bowl lets the odd piece of grass get in there.
Use something to blow those openings clear.... best done by removing carb, but, you can try Kemtool spray solvent on the bottom of the set bowl base after removing the bowl.
Air compressor with a blow tip helps the most.
Sorry ... wish I had a more specific idea....maybe others.
Good luck

MEANING IT NEEDS MORE GAS BECAUSE IT'S GETTING TOO MUCH AIR. Probably the head gasket is blown, Common Remove the head and look for black carbon blowout marks around the gasket Get a new one at the mower shop about $6.00 By the way if you took the carb off and played with the main jet adjust the needle when you have it back together by turning it in BY HAND and back out 1 and a half turns adjust finely once you get it running again. If all of the above fails you could have a piece of grass or ? stuck in the jet but I doubt it ask the question again with the type of engine you have and whether or not it's got overhead valves I will be able to help you better. I will look again tomorrow eve.

Oh......you filled it back up. I bet you dumped the last bit of gas in the can into it, huh?
There was water in the bottom of your gas can and you dumped it into the fuel tank, and it made it's way into the carburator.
You will need to remove the carburator bowl and dump it out.
Allow the gas to flow for a bit untill the gas comes out clean.

See if it'll run with the gas cap off. If it does, the breather is plugged on the cap.
