blower carb PV test
Should the manifold ref pv's hold vacuum using a hand pump? I can mighty vac past the pv value but they both bleed off slowly. Before installing them I could hold vacuum on my tongue with them. The engine is responsive to idle screws and is not pig rich. Is it enough vacuum leak to be an issue?
