You guys should try starting a MM U with a big 4 cylinder.. 4.5" bore, 5" stroke. I can barely do it. Most guys I put on it can't even turn it fast enough, some can't even turn it. It's actually rather funny... I only weigh 150lb and I can start it, but these 200lb he-mans can't... cracks me up. There's alot more muscle to us skinny old farm boys than meets the eye.
