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?
