Got a 90 Evinrude OIS E90ELEUA that is very hard to start, after you get it running it starts good rest of day. It almost seems as if the carburetors are filling up with to much oil, it smokes really bad when trying to start for first time and usually takes about 5 minutes to play with until you can get it to stay running. Primer bulb is tight and I hold in the choke while cranking, it will start but immediately dies unless I keep choking it but even then it will eventually die but you have to choke it to get it to restart so I know its not flooding. If I rev it up while I'm trying to start it, it will rev up but immediately fall on its face and die. Anyway the carbs are filling up with oil while its sitting? Or any other suggestions? Thanks
