1986 trail boss wont turn over

The electrical start doesn’t work right now, no click when I turn the key and press the start, I’m not worried about that right now though. I have to start it with a torque drill because the pull start is broken as well. I cleaned the carburetor once and it turned over easy. I let it sit all night, and now when I try to turn it over with the torque drill it only cranks one rotation before stopping.

I was messing around with it and got it to crank only once today, but it did not start. Now it just wont crank more than one rotation before stopping. It doesn’t feel too easy to turn by hand either. What should I mess with? I don’t really know anything about engines. Cleaning/rebuilding the carb yesterday was the closest I’ve ever got to an engine.
