I finally tried to fix my outboard, but I'm stumped. The motor idles just fine, but as soon as you give it any gas, it spudders and shuts off. it worked fine last time we used it, but it sat for a season without any use. I think my pap put gas with ethanol in it during the last fill up. Any suggestions on what could be the problem? I was thinking maybe it got gunk in it from the ethanol or maybe it even needs a new spark plug. I'm not an engine guy though so maybe you guys can help!
