    got a question...

    just picked up a couple of 70`s and cleaned the carbs and cleaned and set the points.....neither one of them will run unless on full choke....as soon as you try and take the choke off they bog down and die....all the jets are clean and i put new plugs in them as well....any suggestions?

    Look for air leaks between the carb/ rubber boot/ cylinder head area...
