A few years back, Westech actually showed us how to suck start a deuce( at the Haspin rally).
He simply pushed the shutoff cable in, climbed up on the passenger fender, opened up real wide, and put his mouth over the exhaust stack.
After that, it looked like his eyes sank deep into their sockets, his buttocks clenched(very tight), and his ears folded inside out.
One strong inhale and the truck fired up, blowing his lips off the pipe.
He got a little bit of soot in one eye(he said that's normal).
He said it was very important to not swallow, as the carbon monoxide would make you pass out(and you could wake up with your pants missing at the Blue Oyster Club).
He got down, looked around at all the guys watching (with eyes and mouths wide open) and said, "OK, who's next"?...
We all laughed every time we talked to him that afternoon, as his eyes were crossed and he had black lips, but nobody told him.
Oh, and that is NOT in the TM.
