Idle mixture settings on a dual carb set-up

ok thanks Jon

 

ok hopefully this one is good for it I don't mind spending the money as long as it works right, got carbs on the shelf doing nothing

 

got the carbs they came with a mounting spacer that has a piece of metal coming down into the manifold that's shaped in a V , should I use it or not, what the purpose of it?

 

I ended up just going to a 1 carb manifold and it runs good going down the road but at idle it pops out the exhaust I'm thinking maybe a sticky valve but I don't seem to hear it pop while driving although maybe I just don't hear it, is there something in the w-1 that would be causing it to pop while at idle?

 

Thread has become bulky.

Which engine ?

Which W-1 ?

There is nothing in a correctly functioning W-1 that is the proper size for the engine that is going to cause the pop.
