Hey guys new member here. I just purchaced a 742 and it ran fine. I was moving a dirt pile then it just shut down like I ran it out of gas. Filled it back up and now just wants to spin over but not run. I found a ground wire broke on the little thin on the fuel line (whats it do?) It fired right up after fixing the wire. It ran for 20 min then I shut it down and will not start again. Any Ideas? I was thinking on running a new fuel line from the tank to the carb and bypassing the little round thing it has 2 wires on it and have no idea what it does. thanks for the help. Also looking for any spare 742 parts you may have. Thanks hyp
