The pilot circuit in the carb is probably all gum'ed up from the fuel sitting in the carb for years. You will need to remove the carb and fully dissemble, clean, and flush out all passages. The pilot circuit/jet is probably really bad. Make sure to drain the fuel out of the gas tank if it is still old fuel. The modern gas with Ethanol is horrible about attacting water.
There are a lot of modifications to the stock zilla (read as factory fixes) to make them dependable and powerful. Head on over to quadracerhq.com and go into the forum there. This site is specific to the LT250 and LT500 quads.
