Not knowing what your engine is in we're guessing to some extent here. As far as the carb not idling down and the idle screw is not setting on the base, remove the throttle linkage/cable at the carb and see if the throttle will then back down. It could be misadjusted or binding.
The engine needs to idle down to check timing anyway.
