A bosch va pump has no machanical governor. It is done by hydraulics. Any time you get air-or vacuum bubbles in these pumps they will act strange. A worn pump itself can do wild things. I would guess that your metering valve is stuck. Is the center of the throttle linkage turning when you move the lever? Or is the spring override just moving? I have repaired my share of VA pumps. Parts are getting hard to find,but if you know where to look some are still out there. I would be glad to look at this pump for you if you decide to go that route. Al Baker 231/757/0064
