I've got my Thermoquad dialed in really nicely, great A/F #s all around, plugs are good. Timing curve is good. Yesterday I removed the air cleaner and watched the secondary air door open when blipping throttle quickly and the vacuum dropped.
Today, the pull-off is preventing the door opening. The air door is adjusted properly. Not running, I can easily push down on the door and it feels right. Running at idle it is getting vacuum and pulls on the air door. But when I pull the carb open quickly there is no vacuum drop at the pull-off and the air door stays tightly shut.
What am I missing here???
