- Hmm. Several suggestions. First find and replace any and all fuel filters
- you can find. Usually there's just one, but can be more. Also, you fuel
- pressure sounds a bit low, as does the vacuum, but that may be correct for
- this car. Try the fuel pump second.
-
- If the carb's been rebuilt recently, you may have a power valve that was
- overlooked or improperly installed.
