Rough idle/no rev problem

[tada]

I do have some questions about performing the smoke test. I am assuming that smoke will escape through the air filter box. Is there a way to plug it up without full disassembly? Also, do I need to hold the throttle open while testing? Thanks in advance

You can use some of that special gasket material on the outside intake.

The closed throttle will most likely block the smoke. Introduce the smoke into one of the tubes that comes off the Y connector near the vacuum reservoir - or at the fuel pressure regulator?
