I picked up a Yardman 604 with the twin cylinder 2ohp engine today pretty cheap, to the start the mower, i have to hold back the deck engagement lever and then it's loose till i push it all the way forward to engage the deck. I noticed also looking at the deck there is a cable of some sort that has an end with an eye, I believe its called the brake cable. Where does that hook up at? I went to some diagrams but they are confusing of where everything hooks up at.
