After reading your question it sounded like the smoke was due to fuel leaking on the muffler and or excess fuel entering the combustion chamber. I would due the following diagnostic. In a quite area turn on the ignition switch. You should hear the metallic click of the fuel cutoff solinoid on the carburetor.

I had the same problem with my YTH1848XPT . Believe it or not it is simply a dirty air filter....you must remove the filter and blow it out with an air compressor...or better yet replace it. you can not clean it well enough without the force of the air compressor. Mine works great now.

Hi.

There is gas smell in the carburetor because the engine is not starting and carburetor is flooding.

As first thing ensure that there is spark, pull the spark plug wire and put the end near to engine block while cranking. You will see the spark. If there is no spark, check distribution coil and wires.

If there is spark, check if there is fuel pressure, if there is smell from carb, then the fuel pressure should be Ok.
Once you are sure that the pump is doing its job, and that there is pressure, check the carburetor settings. The mixture is probably too rich or too lean, and for that reason it is not igniting.
If it is not a matter of carburetor settings, then the carb must be taken apart to check carburetor filter.

Starts fine, run fine,for about 2 to 5 min.,then cuts off,sounds like it's not getting the gas.

I have a Husqvarna 125B same problem. Turned out to be a bad gas cap. Doesn't vent properly and starves the engine. I took the gas cap off of my Huqvarna weed eater and put on blower and blower worked fine,
