well looks like i screwed up, i got everything back together and took it for a spin and it lost a lot of low end and doesnt top out as fast:???: maybe if i replace the intake manifold i will get some of that back? i did a lot of porting on the intake manifold. so i gess i need i new head now right?
ok...check for any air leaks. warm engine, turn idle screw up a little, and spray brake wash or carb cleaner all around. where the jug meets the bottom, head, carb/intake connection, intake/jug connection. if your rpms change (up or down) thats where you're sucking air. IF thats what it is. just a thought.
