Can physically stopping the camshaft impact timing and can this be adjusted.
500 series engine is running rough; surging/almost stalling. Acts like a dirty air filter but persists when air filter is removed. Seems to get better if idle is increased...carburetor cleaning helped somewhat. Engine was stopped by encountering twine that wrapped around the camshaft. Twine was removed and engine restarted, but has run rough since this incident.
