Default Re: 50 Merc won't start

Maybe you have done this: Re-check the plug wires for correct firing order. Recheck your initial timing and mark the position. Move the timing a little each way and see if it has any effect.

Getting fuel? Spray carb cleaner down the carbs, crank over.

It takes fuel, compression, and correctly timed ignition to run. If the other s fail, check compression. I doubt compression is the issue, though.
