LearningThe Basics of an In line Four Cylinder Engine Remember
when your dad was able to teach you the basic engineering of a 4
cylinder gas engine just by popping the hood on the family Ford?
Boy, those were the days! This kit is a great introduction to
understanding how the four stokes of an internal combustion gas
engine actually works. With this build-it-yourself kit, you can
watch the spark plugs fire and the valves open and close. There
are over 100 plastic parts that easily screw together.
Appropriate for ages 8 and older. Skill Level II. Powered by 2
“AA” batteries (not included). ** Please note: The color of this
