I have a mid-1990's Mercury Mariner 25hp elec start outboard. I don't think I'm using the enrichener knob properly. It's difficult to start at times, particularly if it sits for one day (but not 4-5 days). I took it into the marina, and they didn't have any problems. They rebuilt the carb for me and tuned it up. I don't think I'm using the "choke" properly, as this motor does not have a traditional choke. It's got a "pull to prime" switch that you pull out 3 times and can turn left and right to adjust idle speed. If it's totally cold, and hasn't run for several days, you pull and push this knob 3 times, leaving it out, to get it started. It will usually start right up. However, the next morning after a run, it will flood if you use this same 3 pump procedure. I've tried less pumps, but it typically floods out and I have to pull the plugs, wait and start again. If you use no pumps, it won't fire. After some pumps, it will eventually start, but only after a lot of fussing. Again, if it sits for days, it seems to be ok. How is this enrichiner supposed to be used (I don't have a manual)? Thanks.

Thanks Snaggs, that's what I'm looking for. When you say you may have to do this several times, do you mean adjust the knob each time, or just that it takes several cranks to start?
