    '77 810 hesitation,stumble

    I just bought a '77 810 wagon,with a bone stock L24 in it.I drove it home and it drove great other than it stumbling when you accelerate. I've looked all over for vaccum leaks,fuel leaks,and everthing else I know to check.It feels like a huge vaccum leak to me,once you get over about 2500rpm,it runs smooth.The valves were recently adjusted,but that doesnt mean it was done right. Any ideas?

    I should pull it off and check the bottom of it,the top looked to be in great shape.If not,i'm thinking it could be a clogged injector. Any idea where to find a steering box,or a rebuild kit? Thanks for the help.
