The air valve is opening too fast meaning the tension on the spring should be increased.

Turn the spring adjusting screw another 1/4 turn. Make sure to have the screw driver in the adj. screw when loosening the lock screw.

25" of vacuum at 1000RPM means you have a really mild camshaft.

Have you checked the air fuel ratio indications on the spark plugs?
