This is a 2004 Merc 15hp two stroke, that had not been started for a few years. I got the motor given to me so that I could salvage the electric start for another motor. I decided to try and get the motor working again. It was running when it was put up, oil was sprayed into cylinders and fuel burned out. I hooked up the gas line and started the engine. It ran rough and then more smoothly. After a few seconds I heard and metallic sound and then it shut down. When I pulled on the crank rope, I fund that there was no compression. I need some help or suggestions on what could have happened and what I could do to repair the engine. If it's time to give up on it, let me know that also.
