I have an OMC 250 on a 22' Starcraft. I took it out on Lake Michigan yesterday and it ran well at first. Starts right up but when it gets warmed up it will not idle and will die. It will start right up if I give it a lot of throttle and it runs good at high RPM's but when I go to engage into drive it will die. I had to manually keep the throttle up with another person until I engaged into drive. It will die if I am at low speed, probably won't be able to troll. I am thinking it needs some carborator adjustment. It has a 4 barrel Holley. Any suggestions to get this running good would be appreciated. Thanks.
