Take the top off of the carb and make sure the bowl is full. Put a cover of some kind (i use aluminum file as it easily conforms to the shape of the carb) and let it sit overnight. If the fuel level in the bowl is lower the next day, it is indicative of a leaking power valve. This is the last step I take when rebuilding a 94. I have found a leaker or two over the years, even with new parts.
