Can someone tell me if its okay to block that smog diaphram fitting on the carb. Its the bugger that has a small cover with 2 screws and a small hose attached to a 90 degree fitting. I have it connected to the fitting in the intake manifold and I think its causing problems. I think the intake pressure is causing it to be open all of the time giving me a rough idel. WHat comes with the smog block off kit> Someone help me please..
