Best way to clean the inside of the engine?
If used just install engine on engine stand and use cleaner with bristle brush.
If rebuilding the parts should have been cleaned before you start putting it together.
If new then cleaning with paint thinner should work.
If you try to clean by running the engine then you are too late and time to rebuild, again.
