Hi larryhannah6...

Make sure you are getting spark at the spark plug, to do this:
Remove your spark plug and check to be sure you are getting a bright blue spark at the spark plug.
You do this by grounding the plug on the head of the engine and pulling the crank rope...watching the plug for spark.
If you are getting a nice blue spark then skip A below and go to B.
A...If you do not get a nice blue spark then you may need to replace the electronic module.
Note: If you have to replace the module be sure to measure the position it is in, it is critical to starting.
Take a picture for later reassembly.
B...Also take some fine grit sandpaper (not emery) and lightly sand the flywheel where the magnet is located to clean any rust or corrosion from the magnet area.
Then follow the procedure below:
------------------------------------------------------------------------------------------------------------------------
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:
Write down on a piece of paper and or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.
Mark each piece with a awl, or some kind of sharp instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using a very small shot of starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line/s condition...after a while they will degrade and need replacement.
Check/Clean/Replace your fuel filter if you have one.
When you remove your fuel lines from the carburetor be sure to make a drawing or take a picture of how the lines are connected to the carburetor.
Also a good time to take a picture for later reference for reassembly.
If the generator is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Once you have your carburetor cleaned/rebuilt that should solve your problem.
Please take time to rate me thumbs up

I know this is an old post, but I just had this same situation. Inherited a unit from my father in law and it had be sitting about a year. I drained the gas tank (disconnect fuel line and pressurize tank inlet with shop vac) and flushed out fuel lines and replace fuel filter, air filter, oil and filter. Cleaned and lubricated all carb and choke mechanisms. Sprayed a bunch of carb cleaner and let it soak. Put in fresh gas. Cranked and cranked and cranked. Did not start right away, but stuck with it. I put some gas in a syringe used for injecting meat (just so you know the size) and remove everything above the carb venturi. Put about 1 cc of gas directly in the carb and cranked. it started and ran until that gas burned up (about 2 seconds). It ran ok but wasn't getting fuel so I suspected the fuel pump. Kept at it and repeated this about 15 to 20 times and noticed that it would run just a wee but longer each time. Until finally it caught and ran strong. Put everything back and it is in great shape. Hope that helps. Also, I noticed there was quite a bit of moisture in the muffler. This sputtered out until it got out enough to evaporate it all out. I now keep it covered when not in use - something I am not sure my father in law did.

Rated Output at 20% Duty Cycle 150 A at 16 VAC
150 A at 16 VDC Welding Amperage Ranges AC/DC 10 - 165A Max. Open-Circuit Voltage 80 V Amps Input at Rated Output AC-230V: 21A
DC-230V: 23A You need to configure the machine to specifications of the material you going to weld.That is :
-The material of the job
-And the proper amperage to use for the material.
-For aluminum you will use A/C
-Stainless Steele / Chrome Molly D/C

Aluminum MIG Welding
1. The best feeding of wire for aluminum is done with a spool gun. If you can't use a spool gun, use the shortest gun possible and keep the gun as straight as possible. Use Argon only for shielding gas. Only use a push gun technique when welding aluminum. 2. If you are having feeding problems, one thing you can try is a contact tip that is one size bigger than your wire. 3. The most common wire type is ER4043 for all-purpose work. ER5356 is a stiffer wire (easier to feed), and is used when more rigid, higher-strength weld properties are needed. 4. Clean the aluminum before welding, to remove the oxide layer. Use a stainless steel wire brush used only for cleaning aluminum. 5. Fill the crater at the end of the weld to avoid a crack. One way to do this is to dwell in the weld pool for a second at the end of the weld.

It looks like Hobart made 3 different versions of the 10,000. If you go to their website and enter the model # (and serial #), you can download the exact owners manual with complete parts listing (according to their site). The website is: http://www.hobartwelders.com/service/owners-manuals

The part should be available from them..or with the part number, you can google it and see what is out there in the secondary market.

Hope this helps
