Why is the spool retainer hard to turn on my Homelite UT21967?

How to start a Homelite UT21967 that won't start?
If your Homelite Trimmer engine won't start, begin by checking for a spark. Remove the spark plug, re-attach the spark plug cap, and lay the spark plug on the metal cylinder. Pull the starter rope and look for a spark at the spark plug tip. If there's no spark, try again with a new spark plug. Next, push the primer bulb until it's full of fuel. If it doesn't fill, the primary fuel delivery system might be blocked, and you should contact a servicing dealer. If the primer bulb fills, the engine might be flooded. Remove the spark plug and turn the trimmer so the spark plug hole faces the ground. Rotate the choke dial to the 'RUN' position and pull the starter cord 10 to 15 times to clear excess fuel. Clean and reinstall the spark plug. Pull the starter three times with the choke dial at 'RUN'...
