Kenth:
Is the crossover channel in intake open or did someone close it?

I don't understand what you are asking.  What is the crossover channel?

Kenth:
Crossover channel marked yellow. It heats the manifold for a functional choke and helps convert liquid fuel into a combustible gas.

There has be no change from stock with the manifold.

Jeff K:
I've had a few that just didn't want to work right. I end up putting a cable on them and every single time I was so happy I did that. If you do use the cable, keep the fast idle cam operational.
