Question

Answer
Without actually hearing this ticking noise it could be most anything.

The most common noises are caused by the plastic flywheel cover hitting the flywheel. This is especially noticeable when we have COLD weather and you firts strat it in the morning. As the plastic cover warms up the noise sometimes gets quieter and or goes away completly.
