What should be inspected after removing the closure plate from the crankcase?

After removing the closure plate from the crankcase, it is essential to inspect the crankshaft and camshaft for shims. This inspection is vital because shims are used to adjust the clearance between these components, which can significantly affect engine performance. Proper spacing ensures that the engine operates smoothly and prevents undue wear on the engine parts. If the clearance is improper, it can lead to increased friction, overheating, and eventual failure of the engine components.

In this context, inspecting the crankshaft and camshaft for shims helps determine whether adjustments are necessary for optimal engine operation. This maintenance practice is crucial in small engine technology, as it contributes to the longevity and efficiency of the engine.

The other options focus on different components or systems that, while important, are not directly related to the inspection following the removal of the closure plate from the crankcase.
