OS 70 4 Stroke
 

I checked my engine with the needle valve completely closed (lean), and hooked a piece of gas line to the intake of the carb.

I can blow through it.

What is my next step to correct this.

The needle valve is fine.

I tried a new one, and it does the same thing.

I talked to you on this in another thread, and you told me what the problem was now I wonder if there is a way to correct?

Bing,

From your description, it sounds like the only solution to your difficulty would be to replace the carburetor body.
