Hey guys, I have a "Brand new to me" 1971 Evinrude 25 hp Sportster. I cleaned the carb, replaced the plugs, and I also ran sea foam through it and let it set over night. I then ran a good, clean mix of gas/oil into it. At this point it will start and run only for a short time(30-45 secs) before it cuts out. It will run lomger if I really put the throttle to it, but eventually dies. My air valve is open on my gas tank and it sounds like it is trying to stay running. I know it stilll needs some fine tuning and I think it will stay running. Any ideas? Now for my main problem, I replaced the impeller and as I reassembled the unit, somehow I turned the gear rod and now it will not switch into reverse without turning the propeller 1/4 turn. I hope this makes sense to someone. I attached the water line correctly and everthying else. I do not have a book on this motor, yet. Is there a way to align the gear rod so it will shift into gear? Any help and /or ideas will be greatly appreciated. By the way, I am putting this onto an aluminum 13.5' starcraft seafarer. I am in the process of redoing everything to it. I wish I had taken before pictures.
