Algodoo

this is my first inline 4 spring engine and spring link so pls no hate
credits to FUNCREATOR for tachometer design
icreased smoothness of engine
controlls
i = lock/unlock engine
shift = starter
up arrow = throtle
t = TURBO
dont worry if pistions get missiligned, when the engine starts the pistons allign again.

this is free to use, as long as you give credits, like i did with the tachometer
