Weber carb/hoses

I have a 1986 Mazda b2200. I just ordered myself a Weber carb. The only thing is that those hoses that connect to the header to the carb, I don't know what to do with them. Do I just plug them up?

Yes. Some remove them and plug them with lug nuts (on the header), crimp the pipes or block the pipes.

Before you do all that make sure your area (county) doesn't have emissions testing.

I made a block off plate for the two hoses, down near the exhaust attachment.
