Re: 1973 85hp evinrude wont start

Welcome to iboats. There are things that you must do when acquiring a used engine. Number one is to get a manual. You can order one here (top left on this page)or go to the library until it is received and see if they have one for your engine. Use the search function at the topof the page and check threads on won't start. I would go through the FAQ's first if it were me. Check these out and then get back to us. I would assume that the carbs probably need rebuilt and you still may have a bad powerpack. Make sure you test compression before you try other stuff. If you have a bad cylinder you are wasting time with other checks.
