Hello,
I searched the forum and didn't find the same topic so I'm hoping somebody can help. When I start the boat from cold it starts right up then runs for a second or two then stalls. I can do this multiple times until the engine warms up then it starts and runs fine. If I rev the engine when it's cold, I can keep it running, even though it runs very rough and I have to keep working the throttle and it smells like it's very rich. I can't figure this one out. It only has about 150 hours on the engine, even though it's about 10 years old. It's never had any ie issues before. Any help would be appreciated!
