This is an 'Edan'. I am spelling it the way that I heard it so don't chastise me if I'm wrong. The acclerator was pull the string which was connected to the throttle. This engine was a one-lung diesel, top speed running through 3 gears about 8 or 10 mph. Pretty fun with the chug-chug-chug effect. Home-brewed all the way, each local shop has its own distinctive style of construction and wonderful paint jobs.
