If the carb snaps shut - is this with the engine running or stopped?
If the slide is worn, when there is no intake manifold vacuum the slide will move up and down fine, but when running under a high load condition (ie hill climbing, wide open throttle) it's possible vacuum is pulling the slide against the side of the carb bodyand it sticks. Are there any wear marks on either the slide or the sides of the hole? How old is the carb?
Somewhere I've seen references to air flow through the carb at WOT being enough to hold the slide up but can't find it.
