Awesome info guys! 

I did a full carb rebuild and I want to say the pilot was a 30 but I'm just going off memory.  I dropped the main jet down to a 260 today (it's very cold here in Michigan) and it still seems pretty rich when reading the plug. 

Quick question….Do i need to adjust the long needle that is attached to the slide up or down with that clip and what does that do exactly? 

Be careful trying to jet the carburetor by "reading" the spark plug.  I have many 55 drums full of burned pistons that customers said that the spark plug indicated their jetting as safe.  Cold weather requires the jet sizes to be increased not reduced in size.
