Guys,As I recall, the left hand rested on the top of the radiator, right handgrasped the crank handle with your fingers gripping the handle and NOT yourthumb gripping, slowly turning the crank so as to position the crank handleat what would be about the 7 o'clock position and up against somecompression, and smartly pull up on the crank.Not wrapping your thumb around the handle was the advised way 'cause if theengine kicks back the crank could slip out of your hand easily and only slapyour forearm smartly and not rip off your thumb in the process.Now, on the car installation, the flywheel is at the other end of the enginefrom you as you would crank it and it would turn in a clockwise direction,as viewed from the front of the car. And since the prop is attached at theflywheel end of the crank it turns in a clockwise direction when viewed fromthe cockpit of the Piet, or counter clockwise when propping the engine.So you would offset the leading edge of the vertical stabilizer to the leftso it will force the nose to the right, countering the left-turningtendency.Rodger ChildsPiet in progress________________________________________________________________________________
