" I have a 1972-1975 Mercury 4.5 hp outboard. The motor was cranking fine but I was fishing one day and I tried to crank it and it ran for a second, sputtering the whole time, then it died and wouldn't crank again and hasn't cranked right since. I brought it home to work on it and noticed my ignition coil was broken and I knew my spark plug was old so I replaced the coil, wire, and plug. I then took my carburetor off and cleaned it well. It will almost crank sometimes but if it does it doesn't run well and cuts out and dies. Any ideas would be appreciated. "
