[QUOTE="lugoismad, post: 386117, member: 16518"] I posted about this on thehulltruth.com as well since its more active https://www.thehulltruth.com/boating-forum/673047-carb-adjustment-help-25hp-omc.html But, thought I'd ask here as well since you guys have more experience with small motors. Engine runs but dies after idling about 30 seconds, or dies if you take it above a high idle within about 2 seconds. I rebuilt the fuel pump. Definitely getting fuel now - I confirmed it is delivering fuel. Engine will idle for about 30 seconds before cutting out. If you take it above about 1/3rd throttle it dies immediately. Its very hard to restart it and takes 20-25 seconds of cranking usually. It will start up the first time almost immediately, but subsequent restarts are very hard. I've taken the carb apart and cleaned the heck out of it. I don't have much experience adjusting a carb. Does this sound like a carb issue? I'm wondering if it could be a coil pack, since it runs well cold, but starts acting worse as it warms up. I also noticed a nasty ring of oil in the test bucket.
