2013 S40 dies when given gas
 

My 2013 Suzuki Boulevard S40 has been sitting for four years. I finally have an opportunity to fix it up and get it road ready again, but I am running into trouble. It will start just fine and will stay on during the start-up procedure. However, when I let it idle without the choke it dies 1-2 min later. If I give it any gas it dies immediately.

Here is what I have done so far:

Replace the old gas

Inspected fuel tank for rust

Checked fuel and air lines for blockage

Took apart and cleaned the petcock

Took apart and cleaned the carburetor

Adjusted the idle screw

Replace the battery

Replaced spark plug

Replaced air filter



Everything I have read suggests that its a dirty carb, but I cleaned it and I am still having this problem. Not sure what else I can try. Any help would be greatly appreciated.

Try running the carb through a sonic cleaner. 4 years is a long time for a carb.
