" I have a 1985 Yamaha 9.9 4-s

" I have a 1985 Yamaha 9.9 4-stroke which will start with starting fluid and continues to run as long as I give it throttle, it dies when I let off. Will only restart with starter fluid. The carb has been removed and cleaned. A check for spark revealed a very weak spark. Any suggestions?
Does any one know how to check the powerpack? "
