I have a 2 year old Chicago Electric 90 amp Flux wire welder that was used once and stored. I tried to use it today and run it for about 20 seconds to adjust wire feed.it worked well and then i started to lay a bead and it stopped arcing.I checked ground and connections and it will not even arc if you touch cables together. everything else is working.

Your question is incomplete. But since I see the trouble is with the "spood" I would suggest just reusing the spool from the Chinese wire. You can transfer all of it in a few minutes using a battery operated drill, 1/4-20 x 3-inch carriage bolt, 2 1/4 inch fender washers and a 1/4-20 nut (or two). Hold the new wire on a dowel or screwdriver (let your friend help). Spin the old spool on the drill using the bolt and other hardware mentioned. Be sure to wind it so that the feed direction will be correct, but I suspect the Chinese spool is not directional. Go slow and guide the wire with your fingers - wear cotton or leather glove.
Use the .030 flux core wire with the amperage settings for .023 solid. If you cannot find .023 settings then just set low power first and play with it to see what works.
have you tried adjusting the tension on the flux wire? before you start feeding the wire into it make sure there isnt any kinks in the wire. seems like it doesnt take much for it to bind up once you get start welding with it im sure you will run into this problem quite allot. usually its from welding the wire to the tip. i have to be honest it can ve a pain in the ***

Usually a flux core only welds steel. It is a higher penetration weld than a MIG. Usually it acts similar to 6011 rods in SMA (Shielded Metal Arc) welding -- a.k.a. stick welding -- if you're familiar with that. I don't believe there is such a thing as flux wire for aluminum. There may be stainless wire for it, but I've never seen it. It probably could also be used for building up cast iron and cast steel, but nothing structural. I have a Chicago Electric one and I love it -- simple and it penetrates hard. My 90 amp will weld to 3/8" without breaking a sweat and if I baby it will go to 1/2" or better. It is difficult to go much lower than 12 or 14 gauge though due to the high penetration.
if you are using flux core that might be why, flux core burns hotter, try using 75/25 or more argon than co2, as your gas, the gas will keep it a little cooler, keep your amps down and match the wire speed to the amps, which would be slower wire speed
Are you using combination argon/co2 gas? You need a flow regulator and should have it set for about 10cfm. Note that this is different than a pressure regulator. The problem you note is a result of inadequate or improper gas.
