Here is a pic of the pull-off. I used to do them in house but am currently sending them to an outside source to be "rebuilt" correctly.
They install the correct spring so the pull-off is fully applied at 5-6" vacuum and put a restriction in the inlet to time the release to prevent stumble/hesitation/bog going quickly to full throttle. That's why mine cost $30 and the POS stock ones are $10 shipped via Ebay.......
