Only will start when I give carbs a shot of starter fluid! Runs great after it's started. Sometimes stalls when put in reverse/forward when cold. I tried the manual choke in case the electric wasn't working( no luck), replaced inline fuel filter, bulb pumps up hard and like I said it runs great after started ( And warmed up a bit). I can't find any videos on how to remove carbs ( 4cyl 2 carbs) 1984 75hp 2 stroke mercury
