Question about Husqvarna Riding Lawn Mower 42 Inch Cut Yth2042
Tracking down fuel problems.
Do your self a favor, leave the gas cap off and turn the outlet air on your compressor down below 20 psi. If the tank is nearly full you will blow gas out of the tank. Do this outside if possible; at the very least you need a well ventilated area. After blowing air from the air filter back to the tank, you may have to reverse the process and pressurize the tank to get the fuel started. I place my hand over the open tank and hold the air hose between the joint of my thumb and forefinger to seal the tank, and then squeeze the trigger. Once you have a good fuel flow out the line to the filter, put on a FRESH FILTER. Try cranking the engine. If it still does not start move on to the fuel pump and carburetor
NOTE: Connect a volt meter across the two battery posts. If battery voltage drops below 9 volts when cranking or while the engine is running, the fuel cut off solenoid will not function. That means the engine will not start or will die soon after starting. So check your battery voltage before, during, and after cranking. If the battery voltage is good before but drops below 9 volts while cranking this is generally a sign the battery has one or more bad cells. Replace the battery. If the battery is in fact good, and the voltage is still dropping, you may have a bad starter motor which is drawing too much amperage.
If you find this fuel checkup does not solve the problem, repost your question with updated info and I will walk you through the next step. Tracking down a spark problem; yes, your problem could involve the coil. (Not as likely as fuel)

I if it dies when it gets hot, its mainly the coils, replace it I you have 2 of them replace both (coils can be expensive do a little shopping around to get the best price first) , as far as sputter clean your carb and replace the carb-kit. here's a tip for future reference - when setting your new coil place the magnet in front of the coils mount and place a regular business card between the coil and the magnet to give it the right space to make your spark then mount the coil and repeat for the other, its not complicated as far as checking your fuel pump just unhook he gasline GOING to you carb and place a clear cup or jug to catch the gas and turn the key to fully crank your mower to see if its pumping correctly if its shooting out a lot then your fine if its a dribble here and there then replace fuel pump. hope this helps

SOURCE: spitting and sputtering
mine did the same, I found out that the high speed jet was clogged, I pulled the fuel line off the filtor(going to the carb), stuck the line into a mixture of half gas half carb cleaner, I fanned it up and in 2 or 3 minutes it started running well, hope this helps.

Does it have a fuel pump or is it gravity fed? If gravity fed, when you rebuilt the carb, did you make sure that the main (power) jet orifice was totally clean? No varnish or residue in the hole. Pressurized air or carb cleaner spray into the jet is a good way to test flow restrictions. It sounds like a clogged main jet or a vacuum leak at the carb to manifold gasket. You might want to flush the gas tank and replace the gas cap also, as evaporating fuel over time will leave behind varnish deposits if the cap doesn't seal, even though it is a vented cap.

You need carburetor work.
Youwill need to disassemble the carburetor and spray withcarb.cleaner.
Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.
If the carb. parts are more than 4 years old, you may have to replace them.
The smoke is more than likely because it is flooding. There's too much fuel getting into the carburetor. The choke may be sticking.
If you need further assistance just let me know.
