Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Welcome to Empires!

The knob may be removed.  Either the pointy end of
the screw or the seat it fits into is damaged or
coated with lime.  In fact, the entire throttle
may be removed for cleaning.  These engines were
made to be disassembled - but not the heating element.   

Good Luck,
Wayne
