How do cam journals look? Because they can get worn out to point where it wont run. Or in my case it runs but ticks like a sewing machine going down road. At that point need new head. Even though i only have 5 psi of compression i have auto mac compression tester runs on batteries so it could be wrong but starts every time first kick very easy to start 5 year old can start it easily. Just ticks after few seconds of running. I think you are going to find out you have similar problems i had all same problems. Just from others trying to figure it out you probably will get it but just wait ticking will start. Gotta pull cam completely out if its bad you will definitely see what im talking about.
