it's an 84 Evinrude 90....just rebuilt, and it runs great!! fires right up and idles just fine cold. But as the engine warms up and runs for a while it won't idle at all? and dies over and over. I thought about turning the idle screw up but then I think it would idle too fast when the engine is cold...also sometimes the engine won't start right up when it warm? it acts like its flooded..but just a quick touch of the key starts it up when it's cold! any thoughts? new plugs maybe?? Thanks!!
