In this video we install primary throttle shaft brass bushings to remove slop and ensure an air tight fit. We also seal up the casting plugs to correct a well known Quadrajet defect whereby gasoline leaks from the bowl down into the intake manifold. Some may elect to bore out the well plugs,
tap them and screw in replacement plugs - and THEN apply epoxy.
This is perfectly fine. What I am doing by simply applying epoxy is
somewhat of a risk but it's cheap! It may in fact leak down the
road. If it does I'll take it apart again! Both of these issues greatly
affect idle quality and fuel economy.
