I dont know a lot about small engines so here it is. My engine will start and run just fine most of the time. However after a few hours of running followed by a few hours of sittings my engine wont crank over. I replaced my spark plugs and found that they have a lot of fuel on them after the engine has been running then sits for a while. what can i do to fix this its not allowing the engine to crank over untill they are dry again.

Welcome to iboats.

Please define "engine won't crank" ? Do you mean the starter will not work or will not turn the engine?
