94 merc 40 hp 4 cyl 2 stroker will not start. Starter spins motor fine, has spark, primer bulb firm, kill switch is on. plugs are not wet nor showing signs of getting fuel. new ignition switch and external harness. neutral switch checks out ok. Engine was drained of fuel prior to my purchasing it from Army corps of engineers. Any thoughts on what the problem might be?

Squirt a little fuel in the carbs to see if it will start

Maybe the needle/seats are stuck closed? Bad fuel pump? Follow Laddies suggestion & toss in some fuel mixture into the carbs to test.

Be sure and use pre mix fuel 50:1 or close. Tim
