We recently put a new head gasket on my 8n. I've been working on it here and there getting everything buttoned up and back together on it. I was cranking it over to check for fire the other day. The first few times I hit the starter (just for a few seconds) it cranked over. After that it would just click once. The battery is fully charged, starter is new, cables are clean. The solenoid is the old but it seems to be doing its job as that's where the click comes from. It just occurred to me to rock it in gear to see if it's stuck. Any other suggestions? Just pull it and clean all components again? Thanks!
