"I'm working with a Mercru
"I'm working with a Mercruiser 3.7 LX in an '87 Carver. I pulled the motor and replaced a piston, rings, and bearings. After installation, I fired it up. It ran great for a half hour or so while I asessed the situation. As I was wrapping up my timing light after checking the timing, it just shut off, like someone turned off the ignition. No sputter, no noise, just shut off. Now it cranks normally but won't fire. Upon initial checks, looks like I lost spark. I ran out of time until next weekend. I've got a couple of ideas but wanted to get input from you guys, the experts! Any suggestions? BTW, it's the stock, points ignition."
