I have a 1980 25hp evinrude, and i've done a carb kit, changed the power pack, coils, spark pluge, impeller, ect. It was running fine and then i did all this stuff, to find out it was a power pack issue so it takes even more effort to start my engine now and every time i need to restart i have to choke it, a problem i never had before. I went from 3-5 pulls on cold start to 15+ and from 1 pull on restart to re-choking and 3-5 pulls. What do i need to re-adjust?
