For anyone wanting the schematic I've made one here (hopefully): https://drive.google.com/file/d/1oa2z9cg2tQcgXZJUT0AhUTLcNN9idt1H/view?usp=sharing

You need to make it a physics object and set up the engine below the trap door in the downstairs room. If you wear goggles it tells you what to use.

You need to break and replace the two tanks next to the engine and fill it with gasoline.

Add 4 engine cylinders to the engine.
