Just got this one not too long ago, cannot figure out where the fuel air mixture screw is? It has to have one! Thanks!

 

Welcome to the forums.

You have to tap out the brass plug to get to it. Have one sitting at home that if I were a federal employee I could take a picture of and show you exactly where it is.

Let me see if I have any pics or diagrams here at work.

 

Between remembering to take a picture and where I put the carb last seems to have taken a few days. Sorry.

This is looking at the bottom. (bowl is off carb) On the right side, you see the three post looking things. The one in the middle on yours should have plug in it. Take a smaller drill bit, and be careful not to drill into the screw itself. You'll feel it go through the plug first. It may come out when you reverse the drill, or you may have to pry it out. That is where the air mix screw is.

Sorry for the crappy pic. Wife has the camera somewhere, had to use the cell phone.
