My Ryobi full crank will not start. Has new carburetor, fuel line, fuel filter, spark plug, air cleaner. Am using TruFuel 50:1. Carburetor bulb is full of fuel. Checked spark plug and is getting spark. What am I missing?

The trimmer would not start.
Pulled trimmer apart, found plastic shims on coil broken. This allowed the coil to drop onto the flywheel, which stopped the crank and in turn sheared the flywheel key. If the key shears it will throw the timing off and the engine will not start. The key is made into the flywheel so it had to be replaced. The trimmer runs again.
