I have a Sea King 15 hp. Just tried to run the motor and it only took the second pull to get started but it reved up real high even in start. I had to put it on slow to get it to go down. Then it died and I couldn't ever get it started again. After a while I noticed I didn't open the vent on the fuel tank so I'm sure that might be the problem. Now I've tried several times for a couple days and can't get it to go. Any ideas? Thanks.
