Set the choke, flip the swich and start cranking. Assuming it has the thingy coming off the engine. My first experience with the Lincoln SA whatever it was??? Back in the 70's, I thought they all had to be hand cranked. All I remember was my 130# carcass could get it running just b4 my heart exploded. We were running 120" waterline and my 6'4" B-I-L (awesome dude, swung a 10# sledge with one hand when cleaning off dogs) would take pity on me sometimes and fire it up on the first spin. He was good to have around in a pinch. My other partner in them days was named Jack Daniels and he had a mouth on him....
