This HB .40 cubic inch engine was removed from a Carl Goldberg Skylane 63 model airplane. The engine was gumed up due to caster oil. The plan is to rebuild the engine, bench check and set the mixture controls for proper running and put it back in the Skylane 63.
I loosened the muffler screws
The engine needs a thorough cleaning.
This is a work in progress and takes effore and time.
Thank you for your time.
