went to the lake today to do a little fishing, motor wouldn't start but we trolled around the ramp area and landed some good hybrids. Well, like I said the motor would not start. It is a 99 150 Yammy carbed motor. It is always hard to start anyways but it just would not fire all the way. I kept cranking it and still nothing, I gave it a little throttle and electric and manuel choke but still nothing. I made sure it was getting gas and it was. One thing that I did see is that alot of black crap came out of the exhaust. any ideas one where to start to diagnose the problem would be apprecitated. All the black crap gives me worries. I probably cranked on it for five minutes in total and there was so much crap coming out, is that normal?
