Algodoo

I have added both suggestions from version 1, thanks to
Gent and and Antotabo

The challenge was fine tuning the timing to use low density forces needed to stabilize the engine while moving. Using capillary action to feed fuel injection flow and to adjust fuel spawn/pump speed.

CONTROLS:
F Toggles Fuel on/off
Right arrow to start
C Toggles Clutch
Left arrow to stall/reverse
Down arrow to brake

STARTUP:
Press F to start the fuel. When the tank reaches the red fuel gage, tapp the Right arrow to start the engine. When the engine is running smoothly press C to engage the clutch.

STOPPING:
Press F to turn off the fuel. Once the engine stops firing, press C to disengage the clutch and press the down arrow to brake.

EDIT: I will have to make two versions this one, runs fine in Algodoo but is a bit funny in Phun. Its just re-tuning the mas of a few things.
