    Default Holley Carb issues

    I have a Holley 4150 Double Pumper with Mech. Sec. and i am rebuilding it but I am having a hell of a time getting the metering blocks off the body. Any Idea's? I have heard use a putty knife and be careful. i don't want to break off the plastic vents.

    Wrap a shop rag around the metering block and put it in the vise and tap the body with a rubber mallet while holding it so it doesn't fall once it breaks lose.

    I've always had good luck hitting corner of metering block with plastic/rubber dead blow hammer to get them off. I would suggest against using any putty knife/screwdriver to pry between body and metering block.

    I did hit it with a dead blow hammer HARD! but no luck! I did take a putty knife with some PB Blaster and worked them free. It was tough though...NOW how do you get the gaskets off!?! Will some spray gasket remover work? or whats the best thing...

    I soaked my metering plates and main body in boiling water for 10 mins. It weakened up the existing paper gaskets enough to razor them off.
