I have a Sears 16 hp twin riding mower. When I went to start it the engine didn't suck gas through the gas line. After cleaning the carburetor the engine sucks gas part way to the carburetor. What do I do? How do I check the fuel pump and where do get a new one?

Could the fuel line need blowing out? Or do you need a new spark plug?

I have a Briggs and Stratton engine on my push mower. The primer will not move any gasoline to the carburetor. Once I took the carburetor apart and it worked for a short while. What's wrong and what can I do for a do it yourself repair?

What can I do or does it require professional help? (04/21/2007)
If it doesn't leak: Relax this should be a quick fix. Check the seal between the carburetor & your bowl. Most often this is broken just take it to a parts store & replace it. If it is unbroken, open your bowl & pull the pin that holds the bobber in place. There should be a little plug that goes up & down with the bobber, located under the part of the bobber that you just pulled the pin from. It should come out with the bobber if not then there is your problem. If the bobber is broken where it should hold the plug in place, you either need a new bobber, or a whole new bowl. (It is much harder to find a bobber that fits that bowl, then it is to find a bowl that fits that mower.) If the bobber has the plug with it when it comes out. Then blow air into the place that plug just came from. If it does not go all the way through, get a new bowl. You can fix the old one, but I don't know how to put how to do that into words.
If air comes out of where the where the gas tank attaches to the bowl Blow your hose. If that doesn't work soak it in a mix of old gas & oil for a while. (Preferably 30lb)
If the bowl does leak: you want to check your spark plug by having someone hold it against some mettle. If you get a spark put it back in, & check every hose & pipe between the gas tank & the combustion chamber. (The part you screw the spark plug into.) More then likely you have a clog in something. If you find it, Blow it out with an air hose. If that doesn't work soak it in a mix of old gas & oil for a while. (Preferably 30lb) If it still doesn't work your pistons are probably out of line. If it still doesn't work, go to a pawnshop & buy a new mower. (05/25/2007)

I can't get my lawnmower started. I have changed the fuel, changed the spark plug, changed the air filter, changed the air filter gasket, and changed the oil. When I dump lots of fuel in the carb it will run for about 2 seconds, then it dies. Any suggestions?
