I have a 1992 sunbird boat which has been sitting for 3 yrs. Now the rehab project begins. I have only one issue which is a bummer and I'm pulling my hair out. First the starter went out and now it's replaced. I repalced the plugs and made sure they have spark , which they are. Gas is comming from the tank to the carb and shooting down the carb. The problem is it turns over fine, but doesn't fire up. It's a 4.3 omc engine. The carb is cleaned out and battery is new. Please if anyone has any ideas leave them on here. I would like to have it running tommrow. Thank you
