All you want to do is see if the engine will idle and accelerate under light load. It is unlikely timing is your issue. Heck, you can almost time an engine at idle by ear. Just twist the CAS until the engine smooths out. It will be within a few degrees of 15' BTDC. Certainly close enough to eliminate the problems you are having.
