To prolong the time in between rebuilds and tear downs, go to a hardware store and pick up a 2" stiff bristle paint brush. For abour $1, they are a great investment. We have a couple in the shop, and they are a great thing to have for removing dust and grimes. For hard to reach places we have several PVC bristle brushes, and for head, block, and other hard to get places we use either toothbrushes or pipe cleaners.
The starter issue has already been addressed, so I don't think I need to go over that again.
